Twin image block and auto-image functionality request.

Great easy to use module!

I have two requests for future additions, or sooner.
I use imagefield. So when a image is uploaded to lets say "sites/default/files/images", imagefield parses the image into two seperate images, such as:

MVC-002F.JPG
MVC-002F.JPG.thumb.jpg

So, I have two alike images, with different sizes, and two different names, under one folder.

I feel there should be an option to qualify only a particular image type that could be presented in the U.I. This way, by default only the correct sized images would be displayed automatically. As it is, my site would show both images, one small, and one large of the same image. Possibly a checkbox option of sorts or something like that. Leaving the option to only allow original *or* scaled images. By default, it "sees" all images.

This leads to the second request: Automatically generate image placement, or not. This would allow the administrator an option to manually check-off all images via block module, or have them automatically placed into the display rotation.

Other than that, great work!
Hope to see this happen soon! Thanks
