I am having the same exact problem, which was fixed for a day or two I think. But now it's happening again, so:

I'm having trouble uploading or linking to any image pretty much anywhere in my profile or albums:
Can't change avatar or profile picture by uploading from my computer.
Can't change either by linkin from external source OR any of my albums on psychcentral.
Can't upload any images to any albums.
Tried creating new albums and uploading pics to new album, couldn't do it.

Resized pictures, still no go.

Tried linking from google, photobucket and facebook, nope.

help?

Thanks.

...either I'm hallucinating or now uploading is working but linking isn't.

I'm not sure which.
