Creating thumbnails from .swf files

A friend of mine has suggested securing my photos from being copied from my Gallery by changing the file ext. from .jpg to .swf (I already have a "right-click disable script, but they were still being stolen)

I did a test and it works! No drag and drop. No emailing the page. The only problem is that there is no thumbnail. Apparently, Gallery recognizes the file as an animation.

Does anyone know of a way to get Gallery to build thumbnails from .swf files?

Thanks!
Andrew

None of that will work. The only thing to do, to protect your images is watermarking them.

If I can see it, I can copy it, period, end of story. Gallery treats that as an animation, as you've found out. If you had it converting these to images (thumbnails, etc) I could still grab the image. Heck even if it's in swf format, I'm pretty sure I can get it if I want it.

Watermarking the image and disallowing access to the full image size is the ONLY way to protect your images.

There is no toolkit to generate thumbs from a swf.

I realize that if it's on the web, it can be copied. All of my proofs are watermarked and resized before uploading.

What I'm looking for is a way to prevent dragging and dropping the images onto the desktop and to prevent emailing the page with the image to oneself.

I know there are other ways around it, but these are the two that I would like to secure against.

The .swf looked promising, but without thumbnails, I can't use it.

Any other ideas?

The only other hack I've seen that I think is somewhat worthwhile is using a transparent gif 1x1 image and using CSS to stretch that transparent gif over the entire image. Then if anyone right-clicks and tries to save that image or drags it to their desktop, they get that 1x1 transparent image and not the image behind it.

There was/is an explanation of how to do this in the forums somewhere, I can't find it right now though.
