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)

• Thumbnail quality may be an issue, especially with large original images.
• There is no control of the compression ratio and/or image quality.
• Generation of a large number of thumbnails will monopolize CPU time.
• The PHP script maximum execution time default of 30 seconds will prevent the generation of a large number of thumbnails (but see below for a workaround if your installation is local).
• When working with a remote installation using FTP, it is usually more efficient to generate the thumbnails externally and then FTP them to the galleries/ directory. By default, thumbnails are given the original image name prepended with “TN-”.
• Only .jpg and .png thumbnail image generation is currently supported by PWG. Other image formats will require external thumbnail generation.

• You run PWG on a local machine, without access to the outside world. In this case, it would be safe to edit the 'max_execution_time' parameter in php.ini to a high value, such as 1000. Depending on the speed of your machine, this would allow for the generation of 300-600 thumbnails on average before the script “times out.” If that happens, simply click the “Thumbnail” link, select “All” for “Number of thumbnails to generate,” then submit.
