I'm using PHP to display information from a MySQL database about various issues of a (paper) magazine. GIF thumbnails and PDF proofs of each page are stored like so: /0605/gif/0605_001.gif . . . 0605/gif/0605_999.gif and /0605/pdf/0605_001.pdf . . . 0605/pdf/0605_999.pdf This works fine for all the issues I have online -- I get a GIF thumbnail and a link to the PDF in my PHP-generated report. However, I have older info in the database for which no GIFs, PDFs, or directory structure exists. In those cases, my PHP-generated report will substitute its best guess for what I'm looking for. For example, a call to 0405_001.gif gives me an image and link for 0605_001 . . . when I would have expected (and preferred) a missing image and a broken link. This happens in both IE and Firefox. I don't even know if this is a PHP problem, but the smartest people in the world read these forums, so anyone know what's going on here?/
