How about improving the windows shell so you can include
min and max size for certian types of files.

Also include option so thumbnails are not downloaded.

And I don't mean setting a min size.

I know HTML and you easly detect a link image that could be
a thumbnail. And not download it.

Also how about option to follow meta refresh tags.
Especially when there is no other links in the page.

I do think that should be safe to do. Especailly if you keep
track of where you have been.
