Maybe someone here has some experience with this:

I tried uploading into my album and followed all the requirements — less than 600 x 600 pixels and i think it was under 50K(?). My images are all under 38K, and sizes are all under 500 x 500. I still keep getting that dang message tho, and even tried uploading one at a time to get more detail but ended up getting less. Just my luck.

If anyone has any words of wisdom , please…do share! Thanks
