I fixed a small glitch, which was included in the first releases: input-filenames with spaces were not treated correctly therefore no result was created. Fixed by some string-replacement and setting the IFS-variable which dictates that bash should treat spaces not as separators.
For the next release some filename-embedding into the thumbnail is planned. But this has to happen after the negfix8-conversion else it would alter the conversion itself ..
Download this: version_0.3
Small hint: git offers a really nice exporting-function which will just include the current state of the given branch:
git archive master --output="version_0.3.zip"
