Can't upload photos this time?

[mjcmt]

I used to be able to upload photos and currently have 13 saved. I'm trying to upload 4 more of my current system to post, but they won't upload. An exclamation mark (!) shows up after each file and they don't post. I also tried dragging and dropping and still no luck. All are .jpg under 100kb in size. Am I doing something wrong?

You might have exceeded a file storage limit. I'd say check into that. I use Photobucket so that I don't have to worry about the Audioholics storage limits.

Can I delete a few of my other 13 photos? I can't see how it is done.
