11 months, 3 weeks ago: @ilanamit As Caleb mentioned; try a different browser. I use Firefox and have not had any problems uploading photos.
I do know that as of last week, facebook stopped auto resizing of post photos. All of my earlier posted photos, which appeared fine prior, are now displayed at their original size, which is too wide for the Timeline format. Now if I want my older posts to be displayed correctly, I’ll have to delete, resize and post them again.
I don’t know if this has anything to do with your issue, but you might want to check that your photo is sized properly before uploading.
