PHP Classified Script with Link Bugs & Grafics

Hello, we have a few bug found in our website [login to view URL], hope you can help us: 1) If you click "Top rated ads" you´ll see error. 2) In Greek language at homepage every 5th ot 7th letter appers with &... like ΣΧΟΛ&Et... or GADALA ΕΞΕ&Io... 3) We have to ad a link to the pictures. So that user can also click on picture to see ad and not only the headline. Additional we need about 16 icons for each category: At the moment we see always the "standardfolder". Thank you, George
