On the "Images" page over to the right, there is a drop-down selection where you can select an album for your uploaded images to go into.

Ugh, nothing is more irritating. Audio ads are definitely not something I want on the site, but somehow they slipped through one of our ad networks. They should be disabled now.

Hi Fabian,

You must have recently gotten an IP address of a tor exit node, and now the site thinks you're using tor. I think I've fixed the issue, so please check to see if you can upload now.

Awesome suggestion! I'll see what I can do.

Sorry about that. Pretty sure it's been fixed for good this time!

Thanks so much for reporting this to me. Audio ads are definetily not something we want on the site, and the offending ad network has been disabled. Please let me know if you ever encounter something like this again.

File size is not a direct relationship to image quality. Every image that's uploaded goes through lossless compression (you can do this with jpegs too).

If you're really concerned with image quality then you're going to have to upgrade your account.
