IMAGE MOUNTING ASSEMBLY BACKGROUND 5 The present invention relates to an image Mounting assembly for displaying objects such as photographs, artworks and the like and more particularly relates to an assembly in which the image may be detachably fitted to a support member such as but not limited to a frame. More particularly the invention provides an assembly which allows images to be fitted to a generic 10 frame capable of holding replaceable image substrate mounts, Although the invention will be described with reference to its application as a wall mounted assembly for displaying images, it will be recognised that the assembly has a variety of applications not limited to that to be described. 15 Further, the present invention relates to an assembly For releasably mounting images, and more particularly to the releasable retention of a photograph or the like to a mounting frame. PRIOR ART 20 There are already in existence a number of wall mounted and free standing arrangements which allow display of art works and photographs. The prior art teaches various display assemblies. Numerous innovations for artwork and photograph display have been provided in the prior art. Even though these innovations may be suitable for the specific individual purposes 25 to which they address, they differ from the present invention as hereinafter contrasted. As an example of the prior art, United States Patent No. 6,401,376 discloses a frame type photograph mounting assembly wherein a backing substrate has an adhesive layer on one side and a plurality of retaining pockets on a second side. The retaining pockets are Formed to preclude perforation of the backing substrate. The retaining pockets can forn a frame extending along two, three or all four sides of the photograph, wherein the retaining pocket engages the retained photograph along at least three sides. This arrangement is 5 cumbersome and does not allow releasable attachment of the photograph. There is nevertheless a need to provide a means to allow a display assembly in which images and the like may be releasably displayed such that the image can be readily changed for change of display requirements. In addition there is a long felt want to provide a universal frame 10 assembly which allows releasable attachment of an image bearing substrate. and which will enable simple attachment and detachment from the frame. Therefore, the need exists for a photo or image retention assembly that can retain a photograph or the like and which allows the photo or image to be released without damage and so that when secured to a frame all boundaries of 1.5 the image or photo are adequately but releasably retained and without exposing the photograph or image to damaging alternative adhesives. The need also exists for an assembly in which photographs or images may be easily releasably aligned in a support frame eliminating unintended separation of the photograph or image From the frame and also so that none of the image or 20 photo is obscured by the frame. INVENTION The present invention provides an image mounting assembly for displaying 25 objects such as photographs, artworks and the like and more particularly relates to an assembly in which the image may be detachably fitted to a frame. More particularly the invention according to one embodiment, provides an assembly which allows images to be fitted to a generic frame capable of 2 holding replaceable image substrate mounts which ray be inserted within a recess in the frame. One configuration of the present invention includes a substrate having an adhesive on one planar back surface that engages an opposing surface of a 5 frame support to retain at least a portion of a periphery of the photograph. The present invention provides a useful alternative to the known devices and although the invention will be described with reference to its application as a wall mountable display for displaying images detachable from 10 a mounting frame it will be recognised that the assembly has a variety of applications not limited to that described. In its broadest form the present invention comprises: a mounting assembly for enabling the display of an image; the assembly comprising; 15 a mounting frame defining an internal recess, the frame formed by at least one angle shaped edge member having a first leg fonning a wall of said recess and a second leg forming a backing For said recess; a. substrate member insertable inl the recess and having a back surface and a 20 front surface; the back surface including a magnetised strip located to engage the second leg of the frame to enable the releasable attachment of said member inside the recess to said frame; the front surface of the substrate member forming a display surface capable of holding an image. 25 According to a preferred embodiment, the substrate member is fastened to said second leg of said angled shaped edge member. Preferably, the fastening means is a magnetised strip disposed around the periphery of the substrate member to allow engagement of the full periphery of the substrate member to 3 said second leg. The frame may be square, rectangular, triangular polygona or circular. In another broad form of a method aspect the present invention comprises: a method for display of an image using an assembly comprising; 5 a mounting frame defining an internal recess, the frame formed by at least one angle shaped edge member having a first leg forming a wall of said recess and a second leg forming a backing for said recess; the method comprising the steps of: 10 a) taking a substrate iemiber having a back surface and a front surface capable of holding an image; b) applying to the back surface a magnetized strip about the periphery of the substrate member; c) attaching the substrate member to said second leg of said frame under the 15 magnetism of the magnetic strip so that the substrate member is releasably retained in the recess of the frame such that the image is surrounded by the frame. 20 DETAILED DESCRIPTION The present invention will now be described in more detail according to a preferred but non limiting embodiment and with reference to the accompanying illustrations; wherein Figure 1 shows a perspective view of a mounting assembly according to a 25 preferred embodiment. Figure 2 shows a part cross sectional perspective view of the mounting assembly of Figure 1 according to a preferred embodiment. 4 Referring to figure 1 there is shown a perspective view of an image mounting assembly 1 for displaying objects such as photographs, artworks and the like. Assembly 1 includes a support frane 2 which defines a recess 3 which receives and retains therein substrate member 4. Frame 2 comprises four 5 frame members 5, 6, 7 and 8 which are preferably angle shaped. It will be appreciated by persons skilled in the art that although frame 2 is described as a generally square configuration, numerous shapes and configurations for the shape of the frame are possible such as but not limited to triangular, rectangular circular or polygonal. Peripheral fame members 5, 6, 7 and 8 may 10 be for-med alternatively by one continuous member but in the embodiment shown frame 2 comprises generally L shaped members. A preferred engagement regime will be described with reference to member 7 by way of example since the same engagement regime applies to members 5, 6 and 8. Member 7 comprises a first leg 9 and second leg 10. First leg 9 forms part of a 15 wall 11 which defines recess 3. Second leg 10 forms a peripheral back surface 12 which receives and retains an opposing magnetic strip 14 disposed on back surface 15 of member 4. Similarly for member 6 magnetic strip 16 engages backing surface 17 of second leg member 18 of peripheral member 6. Magnetic strips 19 and 20 respectively engage second leg members 21. and 22 20 of peripheral members 5 and 8. Thus substrate member 4 is releasably engaged to support frame 2 and may be peeled back to be replaced with another member . Alternatively substrate member 4 may have an alternative display image affixed to front surface 23. Frame 2 is preferably generic capable of holding a variety of replaceable image 25 substrate mounts which may be inserted within recess 3. The frame 2 described is formed by at least one angle shaped edge member each having a first leg forming a wall of said recess and a second leg forming a backing for said recess; 5 The fastening magnetised strips may be disposed about the full periphery of the substrate member or they may be intermittently disposed . Thus the contact area of the magnetised strips may be varied according to engagement requirements. Furthermore the contact area may be varied by using 5 alternatives to the magnetised strips such as but not limited to magnetised pads. In use, the assembly may be set up according to the following methodology. Frame 2 is niounted on a surface such as a wall . Substrate member 4 is adapted with an image on front surface 23 . Member 4 is then fitted to frame 2 10 via the magnetised fastening strips. When an image is to be replaced substrate member 4 may be peeled away from franie 2 and a new image fitted to the frame whereupon the substrate with the new image may be returned to the Frame. Figure 2 shows a part cross sectional perspective view of the mounting 15 assembly 1. of figure I according to a prefen-ed embodiment and with corresponding numbering. Referring to figure 2 there is shown mounting assembly I including a support frame 2. which receives and retains substrate member 4 on which a graphic nay be applied. Magnetic strip 16 on substrate 4 engages a slightly recessed 20 metal strip 24. Front surface 23 carries an image to be displayed As before, substrate member 4 is releasably engaged to support frame 2 and may be peeled back to be replaced with another nenber. The frame may be formed of a different material from or the same material as the substrate. The Frame can be formed of a high quality material 25 which reduces degradation to the photograph. The frame preferably engages the image or photograph along three or four sides, thereby enhancing retention of flexible or flimsy photographs. Also according to one embodiment, the 6 frame configuration allows for a selective closure or sealing of the frame to retain the photograph relative to the frame. 5 It will be recognized by persons skilled in the att that numerous variations and modifications may be made to the invention as broadly described herein without departing from the overall spirit and scope of the invention. 10 15 20 25 7
