This happens when someone (last time it was me) attempts to upload
photos that will exceed the size of the remaining space on the
group's photo pages. I have forwarded your message to the group
owner, he alone can fix this. But please, everyone, check the size of
your photos and the remaining space BEFORE uploading. I set the size
at 800x600 and the color depth at 256 colors, which cuts the size
down to about 60kb each.
