I know Wim, and I stated it in my original post
Your works stand-alone.
My script actually also uses the MySQL in the backend to save the meta info about all the images. This means that making it stand-alone would require substantial changes in the script, probably using text files. I was about to do a stand-alone version, but before I got to it, you released yours and because it was pretty much exactly what I wanted to create I saw no point in recreating the wheel
Thanks for your script, it is always great when there are more alternatives where everyone can choose what best suits their needs
