Find & remove files that are duplicates but with different extensions recursively

for f in `comm -1 -2 <(sort <(find contrib/image/ -name *.png | sed 's/\.[^.]*$//')) <(sort <(find contrib/image/ -name *.jpg | sed 's/\.[^.]*$//'))`;do rm "$f.png" && echo "deleted: $f.png";done
Very useful to get rid of backup files or wrong extension files that lure in your folders In this example first I do two searches for all filenames of the two extensions .jpg and .png, then delete the extension and only output the now duplicate files. I loop with these results and print a log and delete the file with the extension I dislike.
Sample Output
deleted: contrib/image/4legs/cat.png
deleted: contrib/image/4legs/dog.png
deleted: contrib/image/withwings/fly.png
