Skitch

This is such an awesome little app! I can see so many different applications for this program, including designer/client collaboration. Why? Each image uploaded is given it's own page where you can grab html code to embed on your page, plus each page has a section where people can leave comments on your image.

Besides that, each image page is, by default, a secret url-meaning only those who know the url can view the page. This would prove handy to send an image to a client, or fellow designer, where they can then leave their comments. To top that off, if the one recieving the image has Skitch themselves, they can click the "skitch it" button & make their annotations to the image. Check out the video below to see what I mean!
