TUAW Tip: Preview has basic text, cropping and editing tools
We sing the praises of plasq's fantastic private beta Skitch tool for making it dead simple to capture, edit and share screenshots with a good variety of online communities, but Mac OS X's own Preview app for viewing images and PDFs isn't without at least a couple of these basic tools. These definitely are not on par with Skitch's capabilities, but as you can see, Preview offers text and oval circling annotation tools, and that Select Tool can help you crop an image (or even multiple pages of a PDF). As far as getting your work out of Preview and off to wherever it's going, the best you can do is save a new copy of the image and manually move or upload it, but hey: if you don't need all the features Skitch has to offer at it's yet-to-be-set commercial price, Preview just might do the job for you.
