Jquery Plugins

My JQuery plugins are here. They are all MIT license, meaning you are free to use them in both private and commercial projects, and free to adapt them however you wish (bug fixes are also very welcome)!

dcookorg_magnifier
Builds on JQuery and JQueryUI, to allow running a magnifying glass over an image and see it magnified. It allows both moving the magnifying glass, and resizing it (which changes the magnification level). It is fully customizable, well-documented and comes with numerous demos.
dcookorg_annotator
Builds on JQuery and JQueryUI, to allow selecting parts of an image (or any DOM item) and adding some text for this. It supplies load/save functions that can be used to pass the data to a back-end server (via form or ajax), or saved to a cookie, etc.
dcookorg_selector_aspect
Builds on JQuery and JQueryUI, to allow selecting parts of an image (or any DOM item) while maintaining a fixed aspect ratio.
get_percentage_position
This is a plugin, that builds on JQuery, to give the position/size of a div (or any DOM item) relative to the size of another DOM item.

Let me know of any cool sites or demos you make using any of these plugins (though there is no obligation to do that).
