Basic Photo Editing Bookmarklet

I was showed a small Bookmarklet app last night that was able to have an image uploaded, resized/stretched as well as have text overlayed on top of the image. It was mainly used for pinterest type pins. I want something similar that would allow me to upload photos, save them once I edit them with what I want added. If I do not add a photo I would like for the bookmarklet to allow me to choose background colors and then add my text with font choices, sizing and hopefully alignment. There may be some more features that can be included as well such as the ability to add as many fonts as I would like to it, change background colors, etc. Please feel free to contact me for more information.
