I upload new pictures almost daily and this is a new problem.
I attempted to upload a picture and I get this message
Upload Photo > Error
The file was either too large, or the wrong format. Please upload only GIFs, JPEGs, TIFs or PNGs smaller than 4Mb in size.
The picture is a jpg and it is 100k in size. So thinking the jpg might be corrupt I tried two others and got the same error message.
