I have a site with about 1400 folders so far and about 14,000 files. All the files are .tif images. The script that I have takes the directory and lists the files in it and then also display the first image, and then each image clicked after that. However, it will not display .tif images in internet explorer and it will also not show a thumbnail. I was wondering if anybody could help me out with the reason it will not show a tif image and also the php to create a thumbnail instead of a full size image. The thumbnail size should be 550x330 px

Here is some of the code that I am currently using, thanks to Roman over at http://www.schechtel.de.

$doNotList[] = '^\.'; // every file starting with a dot (.htaccess, .htpasswd)

$doNotList[] = '^index.php$'; // this file (as DBIV is shipped)
$doNotList[] = DESC_FILE_EXT . '$'; // files that contain explanations to image files.
$doNotList[] = '^dbiv-header.txt$'; // this file's content - if present - is displayed at the top of every page that DBIV generates.
$doNotList[] = '^dbiv-footer.txt$'; // this file's content - if present - is displayed at the bottom of every page that DBIV generates.

$displayAsImage[] = '.tif$';
$displayAsImage[] = '.gif$';
$displayAsImage[] = '.TIF$';
$displayAsImage[] = '.bmp$';


define( 'COL_NUM', 3 ); // how many columns shall be used to print a file listing?
define( 'RELEASE_DATE', '2002-10-25' ); // release date of this script

define( 'LIST_DIRS', TRUE ); // shall directories be listed or not?
define( 'MAX_FILENAME_LEN', 25 ); // if a file name is longer than that it will be shortened and '...' will be appended to in the listing.

Any help would be greatly appreciated

ive got 15 bucks in paypal, if you can add those couple lines of code, you can have it
