Hello wjoycem -
there are tools available where you can review your listings for active content on eBay.
One of the better ones is: HERE
Please also keep in mind that eBay is not even going to begin blocking active content in listings until June and we are working towards updating active listings for our customers with regards to the gallery and the counters and will soon have new templates available. Newly created listings on Auctiva and then posted are already using the new gallery and counter (if enabled).
