Resizing image from one field and save result in another field As mentioned on the comments on this question, on my node-editing-form there are fields for WIDTH, HEIGHT, and an IMAGE. I would like to resize the given image by the dimesions WIDTH and HEIGHT and to save the result in another image field. I hope someone could outline (or even concretise) how to build that module.
have you seen Imagefield Focus?

This would give your users a much nicer UI to edit and crop images, and more importantly choose the correct regions to crop.
