Flickr has just partnered up with Picnik, an online photo editor. Now you can edit your photos that you’ve already uploaded onto your Flickr account. I just added the feature to my account. It looks like you can auto-fix, rotate, crop, resize, adjust exposure, adjust colors, sharpen and remove red-eye. There’s also a whole batch of pre-built effects that you can apply like sepia, vignetting, posterize, and the Paris Hilton night vision effect. Looks useful. I’d probably only use it in a bind. Maybe if I needed a quick crop and I was at home.
