ROBIO  I've been looking for an app just like this one, that retains EXIF and TIFF properties in the smaller documents after resizing in bulk. BatchResize'em is one of the few that does. Just a few requests for the next version:

1) The ability to set your own default source and target folders

2) The ability to set your own default size or percentage

3) The ability to turn OFF the app making a thumbnail for each resized photo (I'm resizing to reduce the file sizes, I don't need an extra 50k added for an icon)

4) Have the progress info in its own window instead of having it take over part of the Menu bar

5) Or at least make all these requests options in Preferences - which this app definitely needs.

With these additions, BatchResize'em would easily be a 5-star app to me.

Also, there does seem to be a bit of a bug relating to having the same folder as both source and target — when I try this the app closes (bombs?) without doing any resizing.
