The copy/move image comparison dialog has "Replace all" and "Skip all", but for reasons unknown is missing "Rename all". However, this is a valid choice if you want to copy/move a bulk of images into an existing directory *quickly* and really don't care about dupes. See my other ticket "skip dupes" which ensures that this choice makes even more sense.
Suggestion: Add "Rename all" to copy/move image comparison dialog box.
"Rename all" on copy/move
