Can a jpeg be uncropped after it has been saved?

Question

I know everyone says you can't uncrop a .jpg image after it has been saved because the data is deleted. I have an image that has been cropped and when opened all you can see is the cropped selection. However, when you simply look at a preview of the image in windows explorer for example, the image is still whole. I can't seem to restore the entire image, but that data can't be lost as it is still available in the preview. Even if i could get the preview open so I could blow it up, that would be enough. Is there ANY way to do this?

Answer 1

when you save a cropped jpeg, then you can't change it, as it has already been saved. you have to go back to the original and save it how you want
