### Cleanup
rm ./project_*.tif
rm ./project.pto

### Check for cache directory, if not -- build
if [ ! -e ./cache ]; then
/bin/mkdir cache

    for FILE in ./*.JPG ;
    do
      FILE480x480=`echo $FILE | sed 's/.JPG$/.png/'` ;

      /usr/bin/convert -compress LZW -resize 25x25 $FILE cache/$FILE25x25;
