Next time you just need to make a few quick tweaks to an image, instead of firing up Photoshop maybe you should try out Aviary. Available online for a while, it’s gotten great reviews as an entirely web-based image editor, and as of this morning is completely and entirely free. Previously available in a “freemium” capacity (basically free, with paid premium features), it is now entirely free.
What the unlocking mainly does is remove a few minor annoyances that free users might have encountered before. You could always save your images and project files on Aviary and download them, but they were viewable by the searching public. Adding a personal watermark was also a paid-only feature, and all the tutorials weren't accessible—but now all that is gratis.

I don’t why see flickr or picasaweb don’t have image editing like this yet. If it’s a big hit on the servers maybe most of the processing could happen locally in a flash app.
