Ok, to counter my bummer parent post here are some things you COULD feasibly implement in javascript: - color tinting (overlay semi-transparent colored elements on an image) - image cut-and-paste (like cropping, place some bounded area of an image in a div with hidden overflow [the copy] and allow that to then be placed over the original image [the paste]) - image gradients, drop shadows, reflections (but these have been done to death and are usually too sluggish to use in a production app) - some neat UI tricks like scroll wheel zooming and gesture-based panning (mootools has some demos which show what's possible - demos.mootools.net) - if you really wanted to kill yourself, you could use flash (degrade to a server-side script) to build a pixel by pixel representation of the image using floated divs and background colors. Then create a JS singleton with your desired methods to be the image buffer's API. Thus, you're granted pixel-level access to the image and could (slowly) do whatever sort of processing you desire in JS.
