This happens a lot on sites like Imgur, Tumblr, and Gfycat. Other sites like Dropbox, YouTube, and Twitter are perfectly fine. It's extremely annoying, imagine I'm trying to upload a 2MB GIF to Imgur, sometimes I'll have to wait 5 goddamn minutes until it'll finally let me do anything, as in I can't even go to another tab, it just locks up. Not just GIFs, but if I'm uploading larger JPGs, smaller JPGs work quite quickly, I think it might be to do with file size. But imagine I upload a 500MB file to Dropbox, it does it straight away, no problems whatsoever. Presumably they have different ways of uploading and whatever Imgur is using isn't very Safari friendly. Sometimes I don't even bother using Safari, I start up Chrome and it'll work perfectly fine, I can't be waiting 5 minutes just to upload a file which should upload instantly. Any idea what the problem could be? Is there a setting I can change? Does anyone else experience these problems?
