Alternative to Infranview?

Hey guys.
One quick question for you...What is a good alternative to Infranview that will work with Mac?

I simply used it to crop pics, resize them, and to bring the file size down for my internet needs. Any suggestions?

ImageWell is a good choice for cropping, resizing etc. For simple format shifting, the included Preview program does a fine job. Of course you can pull out the heavy armor and get GIMP, open source freeware which is remarkably like Photoshop Elements.
