There is also a microsoft program found on the same page as tweakui which adds a right click context menu for re-sizing images to any size you specify

This is so simple

Download the file, if you want the width to be 600 then rename the 400 to 600.

And it puts it into the same folder too!

Nice little ap.  The compression ratio is piss-poor though which kinda spoils it.

Nimrod, theres plenty of apps which will do a batch crop and re-size, the problem is unless your composition is very consistant youll end up cutting off the wrong bits on a lot of them.

Still you could run a batch job and then just manually do the ones which screw up I suppose.

Personally I would probably use Imagemagick (a command line suite of tools which will do nearly anything) but it can be a bit hard to get your head around the syntax.

actually, haiving looked at the OPs link it looks like that proggie will do what you want, scroll down the page until you come to "whats new in version 3.0" and have a gander at image re-targeting support.

For resizing I tend to just record an action resizing and then saving an image at the desired compression, and then using said action in an automate-batch function to do an entire folder in photoshop.
