Signature Issues?

I've been trying to upload a signature and am having big troubles.

When I try to upload an image it says cannot save image or that it is too large.

Then when I try to put the link in like this without the spaces of course it still won't let me put it up.

Anyone able to help out here?

Bumping this up, as I am having the same issue. Is it related to being a newly registered member or low post count?

I am trying to upload a photo into my signature and receive the same message as Buhund_Mom, "cannot save image." My image is smaller than the requirements of 500 x 100. It also looks like I have permissions to upload a photo into my signature.

Text into signature is not a problem.

The same message "cannot save image" came up when I added my avatar, however my photo was added regardless of the message.

Thank you in advance for any assistance!
