Can't upload lot to gallery, file too large

@chips46, yes I think it can be an issue. I had about 15-18 enlarged paintings and about 75-80 smaller paintings (all by other simmers). The lot would not load because the game said it was too big. I had to cut 15-20 paintings and reduce the size of the enlarged paintings before it would load. And the game said the lot was 10 MB. So I do think that using more than 80 of other simmers paintings may cause problems with uploading (depending on the size of the paintings).
