It was an issue with permissions on our website. Due to problems with excessive spammers lately, we had to tighten up the security with new posts. In doing so, it blocked everyone from posting any pics or urls.
All members should be able to post them again, although anyone who is a "registered user" might not be able to.
Try to post some like you used to and let me know if it works now.
Same situation with me, I'm not able to upload any pics.
Works for me. Are you using photobucket?
