XML generator for marking images (example available in Adobe Air, see attachment)

We have a basic XML generator for marking images which has been created last year by a programmer on Vworker. Unfortunately we have no contact with him no more. We also do NOT have the source code to make some adjustment to it. (see attachment for app) The app uploads 2 images and you can manually mark 5 points in it. After marking it generates a XML file with the marked coordinates. We need someone who can rebuild/copy this app and make a few minor adjustments. See below for the requirements. ## Deliverables Detailed Project requirements: * Build/copy the existing app, see attachment for app (not necessary to be build in Adobe Air) * Currently only supports 2 images of both 320x240px. We need it to support all sizes. No size limitations. It only needs to check that both images are the same size. The XML that get generated will use the size of the current 2 images that has been uploaded. * Needs to run on Mac os x
