Hi Piwigo,

I've recently adopted Piwigo as my gallery, and I'm very pleased with Piwigo in general.  However, I am having difficulty generating thumbnails -- please advise:

1.  I batch upload files using FTP FileZilla, usually a couple thousand pics at one time. 

2.  To create thumbnails, I log-in as the administrator, then go to Tools > Thumbnails.

3.  Theer are options to create 5, 10, 20, or all thumbnails.  I choose "all" because with 4,600 pictures, I don't have the luxury of time to create 5 thumbnails at a time ><

4.  Piwigo starts running, then I get a "500 Internal Server Error" with the message "The server encountered an internal error or misconfiguration and was unable to complete your request ..."

5.  I go back to the thumbnail page, and it shows (for example) only 4,100 pictures needed thumbnails.  So I know Piwigo created the thumbnails, but I "crashing" Piwigo in order to generate enough thumbnails in a time-efficient manner ...

Please advise, I would prefer a solution where I don't get an 'internal server error' every time I make my thumbnails ><

Thanks,
Joel
