Be careful when you Photoshop

Photoshop generates small preview images for the pics it produces and hides them in the original image. If you change the image drastically, the preview thumbnail is changed too. But if you don’t make a major change, and instead just crop the picture and resave it under the original file name, the preview thumbnail stays the same and reflects not what your image currently looks like but instead what the original looked like.
