Image resizer - power toy's style program for osx ?

I hope this is the correct forum. I am new to the mac way of life and I have just began to explore my new (and first) mac (17" G4 powerbook).

I have Adobe elements that came with my Canon 300D, so I do have an image resizer, however I was hoping someone had information to a resize program that worked similar to the Microsoft power toys. Simply right click the image and choose the size you wish it to be.

If this exists, please point me in the right direction 🙂

Thanks a million!
