I would like to add a thumbnail format that scales any image to fit a specified width.
So, instead of typing "120x120" I would type "120x0".
And this is how it would resize images:
- 240x100 would become 120x50
- 60x60 would become 120x120
- 90x30 would become 120x40
you get the idea.
The same does long exist in imagecache, but not (yet) in imce.
