Can someone help explain how I can attach pictures to my ad?  I tried copying the URL of the pic, but that didn't work.

...then you copy & paste the photo url into the field at the bottom of the posting window labled picture url.

I know you said you tried the copy and paste and it didn't work. Was the photo on a hosting site? Did you put url in the picture url field?

The Self-Help Center has info on how to do it. Check the link titled Some Info For Providers or Ad Posting Guidelines.

Thank you, I'll try imagecoast.

There were problems in the past with ladies having there photos hosted by imagecoast. I would suggest you use Tinypic.

Having a URL means the picture already exists on the internet. It does not matter where on the internet. You simply pasted the URL into the wrong place. At the very bottom of the edit area there is a box labeled "picture URL". Use that box and take notice the http:// is already present. A common mistake is to end up with that duplicated.
