uploading, resizing image twice

[Anon]

Hi, I was wondering if someone could point me in the right direction in regards to uploading an image and resizing it as a thumbnail and a larger version. I presently just use an upload that lets the user change the filename, and that works fine but have realised that i will need something a bit more complex than that. I have looked a heaps of other peoples code that they have posted but none seems to fit my requirements...would appreciate some guidence
here, if only the GD functions and structure to proform this task...thanks

GD doesn't resample images, it resizes. The 2.0 is Beta and not recommended for production systems.

Use ImageMagick! It's free, performs well, and has every option under the sun, moon, and stars.

Given its open license, I'd be surprised if somebody, somewhere hadn't made a full-featured photoshop-like GUI with it...

Anyway, I don't resize on upload, I resize on view. I use a function call to resize an image, which saves the resized image with a name that includes the x/y coordinates and then spits back the results.

This way I only resize images that are being looked at, with good performance and minimal use of server resources, and I can resize all thumbnails in the site just by changing two variables, and see the result without waiting.
