I Cannot Post Image With Ad

I have 3 ads running but when trying to link images of the items, I get error messages saying links/email address not alowed.????
My images are on my Pbase acct. Is there a fee to post images? I dont see a requirement.
http://www.pbase.com/mdbassman/astronomy ...I added the .jpg extension to the image link but still wont display. ERROR MESSAGE reads-There were errors with your submission, please review the following:
• Links and email addresses are not allowed in your classified ad
Thanks!

You can post images under 500kb but you can't post links in ads, there are too many things going on like people trying to link to ebay auctions, ads in other astronomy equipment venues, and so on. It's a policy, not a question of a fee.

If you attach your pictures directly to your ad text (when prompted to do so) you'll be fine.
