pixer.us: online photo editor Upload your photo online and use this AJAX control panel to fix and modify your photos to your hearts’ content. The response is fast (for now). I modified one of our Jamaica pictures to test. I had some problem with the original (it looks like there are some logistic issues with the software not storing different pictures for different sessions). This might be really useful for bloggers that are editing their blogs or adding pictures where they do not have access to a good photo editor. The following picture was cropped, saturation tweaked, sharpened and randomly modified.
