I can see the ads with photos on yor site:
http://www.hudsonvalleyclassifieds.com/cgi-bin/classified/classified.cgi?action=ViewAd&ID=1229167880&Lang=English
Anyway, reverse the last thing you did wrong if any. For upload images, check
your html url and directory in admin->configuration, check the view ad template, finally check the
files permissions on uploaded files and the upload dirctory. |
