is opportunity to resize images resource-intensive?

Report · Oct 23, 2008

Hello to ALL!!!
I'm trying to make a site with image gallery(for example - pets).And I've thought about optimal size of full image. I've chosen 640x480. And I'm going to use <imageresize> command for images greater than 640/640. But I don't know(in practice) is it a good idea to give opportunity to people to resize their images with code of my site? I mean how resource-intensive this process for a server? And what will happen if for example 500 people will want to make "resize operation" at the same time?

Thank you for your coments/answers!

if you are seriously going to have 500 people resizing at once, I would
suspect you might have issues.
But for just average occasional uploads, you should be fine.
In my work so far with simple or even large batch resizing, I have not
seen any major drag.
In fact I am overall very impressed with the speed and quality of image
resizing in CF8.

a bit OT:
here's a post about some code i've been working on for batch-resizing in
multiple folders, coupled with a jquery photo gallery ... if you *or any
other cf users* are interested, I am looking for testers
