First step, identify all files that end in gif, png and jpg:
mydirectory find /-regextype egrep-iregex '. + \\. (Png
This command will find me all files that have names that will end with a. Png or. Or a gi. Jpg.
Ok we have the list of all images remains to sort the wheat from the chaff for that I'll use the command

mydirectory find /-regextype egrep-iregex '. + \\. (Png Identify 2> erreurs_images.txt
And voila! xargs is used to transmit the results of the previous command (the find) as argument to identify command and then with the STDERR redirection (2>) are harvested all errors in a file for processing.
