You need to play around with execing a shell with args (or simpler put
your commands in a shell script and call that in exec with the filename
as the argument), however in the the best Usenet tradition could I
suggest using mogrify (part of ImageMagick) to alter the files in place,
eg using your find :-

find . -maxdepth 1 -name '*.jpg' -exec mogrify -quality 25 {} +

The + will cause find to run each mogrify with as many files as possible.
