I just noticed that one of my images:[ ImageID=215096 ] is no longer in [ GAMEID=22684 ]'s Image Gallery.
(note: i manipulated the quote to show the code).
Your image never was in that image galery. You image was in the image galery for game [ GAMEID=28279 ]. But this game dosn't exist anymore. If you didn't upload it to a wrong game (which i don't assume), that there must have been two entries for this game, which now got/get merged.
Wait a few days. I assume it's a caching issue. If they don't show up in the other game entry then, contact an admin per geekmail.
