Crap, I was in such a hurry when I posted that message, I didn't have the time to read the details :D

I wonder if it's even possible for a perl script to resize an image in the first place? Perhaps it needs an external application to do it (like GD) anyway?

I'd hate for this idea to come to an end just because it's not possible to resize an image :(

I'll ask the other sites what they use to generale the thumbnails...

why people don't upload image and thumb ?
it will be easier to do

when i was with my old old virtual host.. i needed image magick badly (to resize 4000 images on the fly :D ).. anyhow, they installed it for me.

ask your host.

floleb7 - asking users to make their own thumbnails would indeed be an answer to the problem, but how that works in reality :( Well I just know for a fact that some people might concider that as a waste of time or just a pain in the ass, especially when they know the server could do it for them ;)
The proof is out there. A lot of sites are using some type of script to generate their thumbnails, so it's just a question of finding one that works for everybody. I'm waiting for an answer from a few people to see what they're using to generate their tumbnails. Hopefully they'll be able to give us a hand...

etones - image magick ?

generally the prog for this works but you need to have your own server for use it

Without a doubt :p

Do you know where I could download it?

Your best bet is to support multiple converters, i.e. Netpbm, ImageMajick and GD.

Yeah I'm looking into ImageMagick right now :) The installation notes seem clear enough. I'll install it on my server tomorrow- that is, if the hosting company agrees :D

I got a reply from Jark (Deviantart) and he recommended it. That's what they use on their web site so I think we're definitely on the right track. I just have to find a good script that knows how to use this so I can test it out. Jark would have made one if only he had the time, too bad ;)

but it will require a own server ?

Um.. few problems.

1. ImageMagick is not that easy to install after all. Lots of files... loooots of files.. 618 files (12mb) :(

2. I was told that the application would disrupt our apache server so I won't even be able to test it out :(

I give up... the development of this feature is way too complicated for a beginner like me and I've been struggeling with this idea for months. Guess I'll just have to build the galleries manually until something similar comes along ...

Anyways, thanks for the support guys :)
Peace.
