 optipng for png and gif, jpegoptim for jpeg. both are available in ubuntu as dependencies (our primary platform)

+==========================================
+todo app wise
+- implement jpegoptim
+- implement something for gifs
+- implement drag and drop on table
+- clean up code, make it PEP-8
+- figure out what to do with:
+    - recompress and optipng ( −o7? ) not really doing anything
+    - lockup when opening files (i'd like it to not lock up the file dialog)
+
+todo else
+- figure out dependencies for a .deb/how to make a .deb
+- figure out launchpad repo or something
+- figure out how to make mac and win versions
+
+current dependencies:
+python
+python-qt4
+hurry.filesize (bundled)
