This is a problem. For javascript to detect if an image exists on the server, it must do a HTTP request which takes ~100ms. For PHP to check if that image exists on the same machine, requires 1 sys call or about ~0.01ms. It sounds like you have a bad lightbox implementation. The page should already know if the thumbnail exists, and if a lightbox is possible when the html is sent. _______________________________________________ New York PHP Users Group Community Talk Mailing List http://lists.nyphp.org/mailman/listinfo/talk http://www.nyphp.org/Show-Participation
