Problem getting imagemagick to work with php...

Hiya I need to be able to automatically change the format and size of an image when a user uploads it and using imagemagick's tools seems like the way to go about it. Unfortunately the server I'm using is Windows based and it doesn't have imagemagick installed. I downloaded the Windows imagemagick binaries and the tools work fine locally from the dos prompt. I hoped that uploading these files to a directory on the server would allow my PHP script to use the tools, but either I'm typing in the wrong commands or the tools won't work on the server. When I try this little test script: ***** $file1 = "\\images\\gladius.tiff"; $file2 = "\\images\\gladius.jpg"; $command = "\\imagemagick\\convert ".$file1." ".$file2; $result = system($command); if ($result) { echo("Conversion Done!<br><img src = gladius.jpg>"); } ***** I get: Warning: Unable to fork [\imagemagick\convert \images\gladius.tiff \images\gladius.jpg] in .... I've tried using unix slashes and single slashes. I've also tried running the script in the imagemagick directory - I didn't get the 'fork' error but the system function returned false. I also tried using exec(), passthru() and backticks but none of them worked (backticks gave a weird CGI error message). Anyone know what I'm doing wrong? Does Imagemagick need to be installed in some special place on the server? Thanks Brian
