I was thrilled to see that all the pictures were recovered to the jpg-folder with the correct filenames, but shocked to see that my program was still running! I had to Ctrl + C to end it.
I managed to get the program to close, and I have run Valgrind to weed out some errors. All the pictures are recovered in my jpg-folder, but check50 won't accept them. Here is a link to my check50 sandbox output.
Why is check50 not accepting this result?
