I use this on most sites for straight downloading of jpegs, the problem with some of the epson folders is the thumbs go to html pages with pics embedded before you get to the pic itself. Another big problem is that most people don't bother to name files especially in Epson, therefore you'll find each file named "View" and you'd be prompted about overwriting.
I've used it on other sites where I was able to download a ton of pics but then had to write the extensions in.
Hope this will be of some value.
