The PhpWebGallery Development Team (DT) answer is:

• You're not alone using PWG.
• Currently, close to 40,000 downloads were made last year.
  

Obviously that hasn't resulted in as many new sites rather, some people have downloaded successive new versions of PhpWebGallery and some people, owing to incompatible web-server set ups on some free ISPs, have not been able install PWG correctly.

DT:

• A web-server with support for Php and MySQL.
  

External links to official sites: and

Preferably an Apache server running on Linux.
IIS on a Windows 2000 sever works fine as well.
Mac OSX works also!

• For 10.3.x users, the version of PHP shipped with the O/S is NOT enabled for gd2, which means you will not be able to generate thumbnails (and probably not be able to do other things as well). A binary PHP5 package for 10.3.9 is available here.
• If you end up with a blank page while attempting to generate thumbnails for the first time, you probably don't have a gd-enabled PHP installation. See above.

To give an idea of your space requirements:

• 100 High res images (corresponding to your images) ~75Mb.
  
• 200 800x600px images and thumbnails ~15/20 Mb.
  
• You dont just have to have the gallery on your site (what capacity!).
  
• Videos?

PhP (the elephant): is “the” language behind PhpWebGallery, don't forget this. MySQL: is the database essential for running PhpWebGallery.

If you require more space than is available… less important data can be transfered to a “distant site”, that is to say, a second server containing less frequently accessed data.

If your ISP doesnt appear in the lists below and you know where to add it, please do so.

• Wanadoo (basic package)
• US/UK ISP or any Hosts/Providers are obviously invited to complete list hereunder :) or above :(

• Free
• Club-Internet
• Wanadoo (supplemental package)
