Server Error whenever I'm upload to my personal gallery

I'm experiencing this issue as well and from what I have seen in some other places, the issue is related to  paintings by reference and photos your sim has taken and placed on the walls in the build.  It is frustrating because I have a lot of lots I would like to share on the gallery, with the photos but can only share the tray files outside of the gallery.  The odd thing is the it doesn't happen when I download paintings by reference from rooms on the gallery and put them on the wall.  It only happens when the paintings/photos are ones that my sim painted or took.  I am not sure why EA has not seen this or been able to address it yet.
