The following is a summary of image cleanup procedures you can use, and instructions on how to do them. The images in the previous question were taken in a similar way as the ones in these questions and are covered in the other questions as well. You should be familiar with those procedures, as you should be able to identify the differences between the two. You can usually distinguish between the two at a glance when reviewing images, and if you are doing much more than image cleanup you probably don’t need to worry about that detail. For more background on image cleanup in Photoshop, see the tutorial in the previous link.
How do I find an image if I have an image mask set?
Using the image selection tool in Photoshop, select the desired image. Then hit Select > Expand > Image mask. If the mask is set to only show only selected parts and not the entire image (for instance, when making sure that the window is maximized or the image is saved to a .jpg file, see “Saves on Retouching Options” below), you may have to use the Find Image button.
Saves On Retouching Options: If you have an image mask set so that you can select only certain portions of the image, rather than the entire image, then you only have one option to find the image. Save the image as a .jpg file with the file type JPEG. Then save it using the File > Export menu option (Windows, Mac OS X, or Linux) as either Full image or Image. Save this file, and it will be preserved for future reference (except if you use it to restore a file you were not intended to restore, in which case, see “Restoring or Resizing an Image” below).
Saving a .jpg file is a convenient way to save the image, but it is not a completely foolproof tool. You cannot restore an image that has been saved in a .jpg file. For more information, see Why are .jpg files different than .jpeg files? and Saving a .jpg file in Photoshop: The Process.
Do I need to set up a copy of a .jpg file to restore?
No. You will be able to view (and restore) any saved image in any way that you choose. (See above.) However, you can restore a .jpg file if you wish to.
Do I need to restore a restored .jpeg file?
No, a restored .jpeg
