Scott,
I'm not going to comment on the quality difference between your 1MP pic and the 12MP one. I'd have to assume that's using different cameras...
Regarding showing the 12MP picture here, that isn't going to happen. It would be enormous... Second, you're not going to be able to host that file on any of the photo hosting sites at that size. They ALL reduce the file size to something managable.
What you need to do is take the picture, and resize it to an appropriate size, then host it online somewhere and share it.
I realize that you want to show the whole cue in close detail, but that really isn't a reasonable option on this site.
What I would recommend is shooting a few macro shots of the area in question, and hosting those at a normal size. I'd be surprised if you need more detail than that. For instance, here's a macro I took of a leaf. This file as you're seeing it is MAYBE 0.1 MP... plenty of detail.
Or if you already have the large, detailed image you could crop sections of it into smaller images and share those.
I'm not sure if I've made things more or less confusing... If you want to host large files and share them with people, you could host them somewhere meant for pictures (picasaweb, photobucket, flickr, etc.) and then link there.
Good luck!
