Customizing Image Upload Script

[matthewamzn]

I'm trying to create a second set of thumbnails for my website. This is the attachment part of the script. How can I duplicate the thumbnail generation.

to be honest, that is a ton of code and I'm not going to read through it all

did you just want to reuse existing code for thumbnail generation in another part of the script?

if so maybe move it into a function and then you can call that function everywhere it is needed
