Best thing you could do, would be to give us an example image. Pointing out what you would like to accomplish with this image.
Also, is all that you're asking needed to be done to a single image?
BTW... you'll have to make at least 5 posts to be able to upload images to Gimp Chat, or anything else for that matter.
