It may be replaced.

  FIG. 10 is a flowchart showing a processing procedure for uploading an image to the server 10. This flowchart uploads an image to the server 10 by attaching an image file to an e-mail.

  When communication between the mobile phone 1 and the server 10 is established, an image for image registration in which the image registration request character is a clickable area is displayed on the display screen of the mobile phone 1. When the image registration request character is clicked by the user, the image registration request data is transmitted from the mobile phone 1 to the server (step 41).

  When the image registration request data transmitted from the cellular phone 1 is received by the server 10, data for displaying an activation instruction of a mailer (e-mail transmission program) in which an e-mail destination is set is transmitted from the server 10 to the cellular phone. 1 (step 51).

  When the data for displaying the mailer activation command is received by the cellular phone 1, an image of the mailer activation command is displayed on the display screen of the cellular phone 1 (step 42). Then, the mailer is activated by the user of the mobile phone 1 (step 43). An image file to be registered in the server 10 is attached to the e-mail (step 44), and the e-mail with the image file attached is transmitted from the mobile phone 1 to the server 10 (step 45).

  When the electronic mail transmitted from the mobile phone 1 is received by the server 10 (step 52), the image file attached to the received electronic mail is taken out and stored in the attached image database 17 of the server 10 (step 52). 53).

  FIG. 11 is a flowchart showing another processing procedure for uploading an image to the server 10. This flowchart uploads an image file to the server 10 using a dedicated application program.

  The dedicated application program installed in the mobile phone 1 is activated (step 61). Then, a list of images represented by the image files stored in the memory 7 of the mobile phone 1 is displayed. An image to be uploaded to the server 10 is selected from the displayed images (step 62). An image file representing the selected image is read from the memory 7 of the mobile phone 1 and uploaded to the server 10 (step 63).

  When the image file transmitted from the mobile phone 1 is received by the server 10 (step 71), the received image file is registered in the attached image database 17 in the server 10 (step 72).

  FIG. 12 and FIG. 13 are flowcharts showing the processing procedure between the mobile phone 1 and the server 10 when sending an e-mail with an attached image file.

  In this processing procedure, the data amount of the image file attached to the e-mail is, as described above, the data amount of the e-mail itself, the data amount of the background image, the data amount of the template image, the data amount of the template text, In consideration of the amount of text data input by the user of the mobile phone, etc., adjustment is made so as to be within the maximum data amount of the e-mail.

  When the connection between the cellular phone 1 and the server 10 is established, an existing layout image is generated based on the data stored in the decorative image management database 11 of the server 10 (it goes without saying that it may be generated in advance). No), the existing layout image data for displaying the generated existing layout images as a list is transmitted from the server 10 to the mobile phone 1 (step 91).

  When the existing layout image data transmitted from the server 10 is received by the mobile phone 1, the existing layout images are displayed in a list on the display screen of the mobile phone 1 (step 81).

  FIG. 14 is a list of existing layout images displayed on the display screen of the mobile phone 1. Since the display screen of the mobile phone 1 is relatively small, the entire list image 100 of the existing layout image is rarely displayed at once on the display screen, but the list image 100 of the existing layout image is moved by scrolling. To do. The user of the mobile phone 1 can confirm all the list images 100 of the existing layout images by looking at the display screen.

  The list image 100 of existing layout images includes a first existing layout image 40 and a second existing layout image 103. The first existing layout image 40 has a layout based on the data managed in the decorative image management database 11 by ID00001 as described above. The second existing layout image 103 has a layout based on data managed in the decorative image management database 11 by ID00002. Needless to say, if there are other layout images, those layout images are displayed in the list image 100.

  Below the first existing layout image 40, a first clickable area 102 represented by the characters “use this” is defined. In addition, a second clickable area 104 represented by the characters “use this” is also defined under the second existing layout image 103. When sending an e-mail such that the first existing layout image 40 is displayed in the text area, the first clickable area 102 is clicked by the user of the mobile phone 1. When an e-mail is sent such that the second existing layout image 103 is displayed in the text area, the second clickable area 104 is clicked by the user of the mobile phone 1.

  Returning to FIG. 12, the existing layout image is selected by the user of the mobile phone 1 (step 82). Then, identification data (ID) of the selected existing layout image is transmitted from the mobile phone 1 to the server 10.

  When the identification data transmitted from the mobile phone 1 is received by the server 10, the registered image file registered in the attached image database 17 is read. The read registered image file is transmitted from the server 10 to the mobile phone 1 so that the registered images represented by the read registered image file are displayed in a list (step 92).

  When the registered image file transmitted from the server 10 is received by the mobile phone 1, a list of registered images represented by the registered image file is displayed on the display screen of the mobile phone 1 (step 83). ).

  FIG. 15 is an example of a registered list image.

  In the registered list image 110, a large number of thumbnail images 111 (which will be generated by the server 10) of images registered in the attached image database 17 of the server 10 are displayed. Below each of the thumbnail images 111, a clickable area 112 in which the word “select” is displayed. When one of the clickable areas 112 is clicked by the user of the mobile phone 1, a registered image is selected.

  Returning to FIG. 12, when an image to be attached to the e-mail is selected from the registered list image 110 (step 84), data representing the file name of the selected image is transmitted from the mobile phone 1 to the server 10. Is done.

  Then, data for inquiring whether to change or add the default text (template text) included in the selected existing layout image is transmitted from the server 10 to the mobile phone 1 (step 93).

  When the inquiry data transmitted from the server 10 is received by the mobile phone 1, an image for inquiring whether to change or add the default text is displayed on the display screen of the mobile phone 1. When the default text is changed or added (YES in step 85), the text to be changed or the text to be added is input from the input device 3 of the mobile phone 1 by the user (step 86). Data representing the input text is transmitted from the mobile phone 1 to the server 10. If the default text is not changed or added (NO in step 85), the process in step 86 is skipped. Next, the e-mail address is entered. Data representing the input destination is transmitted from the mobile phone 1 to the server 10.

  Referring to FIG. 13, the background image, template image, template text used for the existing layout image selected by the user of the mobile phone 1 (if the text user changes or adds text) The maximum size (data amount) of the image file attached to the e-mail is calculated in consideration of the respective data amounts of the changed text or the added text) and the reference e-mail structure file (step 94). This calculation process will be described in detail later.

  When the maximum size of the image file to be attached to the e-mail is calculated, the data amount is adjusted so that the data amount of the image file selected by the user as the image file to be attached to the e-mail is less than or equal to the calculated maximum size. (Step 95). It goes without saying that the data amount is not adjusted if the data amount of the image file selected by the user is less than or equal to the calculated data amount.

  Subsequently, an HTML electronic mail is generated (step 96), and the generated HTML electronic mail is transmitted to the destination input by the user of the mobile phone 1 (step 97).

  FIG. 16 and FIG. 17 show the body area of the electronic mail represented by the generated HTML electronic mail.

  The e-mail body area 120 shown in FIG. 16 uses the default text 34 of the existing layout image 40. The body area 120 includes a first template image 32, a second template image 33, and a template text 34 that constitute the existing layout image 40. The attached image area 35 displays an image 121 represented by an attached image file selected by the user.

  When the existing layout image 40 is selected by the user of the mobile phone 1 and neither the template text is changed nor the text is added, an e-mail in which an image as shown in FIG. Sent to the destination entered by the user.

  E-mail body region 130 shown in FIG. 17, but the existing layout image 40 is utilized, is changed default text 34 has been input text by the cellular phone 1 of the user "Hello" 36 body area 120 Is displayed. Similar to the text area 120 shown in FIG. 16, the first template image 32, the second template image 33, and the image 121 represented by the attached image file selected by the user are displayed. Yes.

  An e-mail that uses an existing layout image as it is can be sent, or an e-mail that has texts changed (or added) can be sent.

  FIG. 18 is a flowchart showing the procedure of the attached image file maximum size calculation process (the process of step 94 in FIG. 14).

  When the default text (template text) included in the existing layout image selected by the user is not changed or added (NO in step 141), the data amount is changed by the text input by the user of the mobile phone 1 There is no.
