Batch picture size converter

i have many pictures most of them are wallpapers..is there any way that my web page can dinamicly resize the wallpapers to smaller-size thumbnails so the user doesnt have to wait all the time long..?

even if it doesnt exist something like that, what kind of programs can do that automaticly to me, i tried paint shop pro and it does not seem to have a function like that

when i talk about size, i am not talking about compression, but about picture size in pixels,cm,twips,whatever lol!

tks in advance

photoshop does that. just go to file->automate->web photo gallery.

Yes, photoshop can do it.

There are also a lot of automated image gallery scripts at www.hotscripts.com that resize pictures on the fly to make thumbnails and everything.
