I wrote 3 tools all at different times. One was to convert these bulky TIFF images a photographer gave me to JPEGs that I could access in Photoshop without my computer tiring and dying. The second tool was just a batch JPEG compressor to optimize high quality JPEGs for the web. The last tool was built for renaming files and removing characters that you would not want in file names on the web (things like ? ! and ). Packing all these tools together with a simple interface created RJGIS. RJGIS will read and write JPEGs. RJGIS is available in both a self installing executable and zipped file. RJGIS has been tested and working on Microsoft Windows 98/NT/2000/XP and the new Windows Vista. RJGIS is available in English and Polish.
