I guess I would not run into that issue in my workflow since I very rarely do any type of 'in-place' work on a file. My reasoning being that if something goes wrong you are likely to end up with a corrupted file. Instead I usually write a new file with the old name to a different directory, and if I am certain that worked, then I *might* go back and delete the original. I tend to be a data hoarder to I tend to keep originals.
You will have to do some combination of write to new file, delete original file, and renaming/moving. I would use the file constant to get the temp directory and write a new file with the original name to there. Then I would delete the original jpeg and move the new file into the original directory.
