A photographic mounting system correlates photographs with height by providing a vertically mountable ruler configured to adjustably receive and hold photograph frames at various adjustably selected heights on the ruler. The frames, in turn, hold the photographs, thus allowing placement of the photographs at selected heights on the ruler. Various locking mechanisms are disclosed to secure the frames to the ruler and prevent inadvertent or unauthorized removal. Also disclosed is a virtual equivalent of the physical system, the virtual equivalent having a greater variety of possible modifications and a greater amount of information linked to various growth indicia.

1. A growth chart system, comprising: a ruler with an inwardly flared tab slot in a side of said ruler, said tab slot extending along a major portion of said side of said ruler; and a plurality of visual media holders, each having an outwardly flared tab at least loosely fitting within said tab slot, the maximum thickness of said tab being greater than the minimum width of said tab slot, so as to prevent said tab from being pulled laterally out of said tab slot but selectively allowing longitudinal sliding of said tab within said tab slot and thus selective sliding of said media holders along said sides of said ruler; wherein a rear portion of said ruler is recessed to define a flanged keyhole type groove and wherein said system includes a transverse retainer pin movable transversely across said keyhole groove configured to releasably lock a fastener head in said keyhole groove. 2. A system in accordance with claim 1 further comprising a second tab slot on an opposite side of said ruler from said first tab slot, said second tab slot extending along a major portion of opposite side of said ruler. 3. A system in accordance with claim 2 wherein said tab slots are of equal length. 4. A system in accordance with claim 1 wherein said ruler is vertical. 5. A system in accordance with claim 1 wherein said flared tab is discontinuously flared. 6. A system in accordance with claim 5 wherein flaring of said tab is provided by a bead at an outer end of said tab. 7. A system in accordance with claim 6 wherein said bead is circular in cross section. 8. A system in accordance with claim 6 wherein said bead is non-circular. 9. A system in accordance with claim 1 wherein said ruler comprises separate upper and lower portions, a fastener configured to releasably connect said portions and an aligner configured to align said tab slots of said upper and lower portions to form tab slots extending along both said upper and lower portions. 10. A system in accordance with claim 9 wherein said fastener and aligner device are a single element. 11. A system in accordance with claim 9 wherein the fastener is a tongue and said aligner is a groove. 12. A system in accordance with claim 11 wherein the tongue is a flanged bar. 13. A system in accordance with claim 9 wherein the fastener and aligner are on a rear surface of said ruler so as to be hidden when the system is mounted for normal operation. 14. A system in accordance with claim 1 wherein said visual media holders are photographic frames. 15. A system in accordance with claim 14 wherein said photographic frames have a photographic slot adjacent said tab, said photographic slot being obstructed and hidden by said ruler when said tab is located in said tab slot.
