From Leon's thread about the site upgrade:
"Last night we did a server and software migration. It looks as though pictures are not automatically downsizing as they did before, when using this s/w to host them. A help ticket has been put in and I will update this thread as we figure it out. Please let me know of other technical glitches. If a function worked before it should work now.
And a random card This pic had to be downsized to 68k first in order to upload. It was around 500k and worked fine in the system before. The max size of hosting of pics, hosted in this system, is about 87k."

So it looks like we may have to pause the daily card gallery until this issue is resolved unless everyone can find a way to shrink the size of their picture files.
