I am trying to figure out why tif files I upload do not display in Coppermine. They upload and download fine and I am using Image Magick to handle the files. However, CM displays an Icon rather than a thumbnail. Is this an issue related to my web provider and server? ???
tif files as not suitable for the use on the www in the first place - they're too large and image libraries can't deal with them properly. Coppermine doesn't create it as image file, but as document. That's why a generic thumbnail is being displayed. You can upload a custom thumbnail (refer to docs for details). See tif file on demo (http://coppermine-gallery.net/demo/cpg14x/displayimage.php?pos=-460)
