I've this requirement - when user uploads an image, s/he should be able to select an area of image (preferably freestyle selection, but rectangular is okay too) and the coordinates for that selection should be saved and kept for some backend processing in a script.

I checked out few image crop module, but they more or crop the picture and save it (as advertised), is it possible to do the above with tweaking few things, or is there a module which can help for the above requirement??
