Interesting software! I have used JPEGCrops until now but his looks easier to use. But there is something strange on my computer with this app. The crop button is not there on my computer? Is my images to large for the software or something? Is there a key I can push instead of hitting the crop button?

That was a bug relating to the size of input images. Fixed now.

Working perfect now. Thank you! Much easier and quicker than JPEGCrop.
I have one suggestion for future release. Is it possible to make a output folder and keep the originals?

Good to hear that it works better now!

I'll keep the suggestion in mind. But for now the desired effect can be had manually: first copy the image folder and then use BookCrop on the copy.

updated version:
preview height now adapts to screen height.
fix: selection was imprecise in some cases.
new option: crop to subfolder (keep originals).

BookCrop is now updated to version v130622:
.tif input now also works
faster preview thanks to -size command in graphicsmagick
faster crop thanks to jpegtran from libjpeg-turbo (but slower jpegclub jpegtran still works)
fix: find GraphicsMagick path via registry 64bit Windows now works
fix: removed term "lossless" from info

Followed directions as best I could--program worked several time, then would not work, that is, no images in cropped folder.
Attempted to get a new copy of GraphicsMagic--not successful. Message that windows does not know what to do w/23.5mb file of GraphicsMagic
Any other download source?
Thanks,
jim
