Browser Optimization - ebay Template

Dear friends, we have a problem: We developed a ebay template with a nice picture frame. Our ERP is inserting the picture source (link) automatically in the script and import it automatically to ebay. Our problem is: If we have only 7 out of 12 pictures - our ERP will not insert a link in our script. But if it our ERO only insert 7 out of 12 links, some browser do have problems with that. But we need to have this functionallity due to the fact, that the number of pictures per item differs from 1 to 12. How can help us to optimize the picture frame? Our template and some browser shots are included.
