Resize an image?

[Allsop]

I have a Hazel action set up that converts any image I put in it to a JPEG format, I would also like to resize the image automatically, anyone know how I can do this please? Cheers

Someone else with more experience with this should chime in but you can try something like ImageMagick (the commandline version) to do this.

I use this in evernote, and work fine.
It may be helpful for you too (although it may require some adjustment)
