Downloading from another database

[Argento]

I've got a picture database of University research slides that I'm putting into a database. The raw images are about 5 megs each and I've put them on their own seperate database. In another data base I have greatly lowered the resolution etc. to make the pictures about 16K each.

What I want to do is make the 16k version the one that people see on the web, and if they want the image for their lectures I want them to be able to click on the image and have it download the raw 5 meg image. How do I get filemaker to match the files, and make them be able to download the raw image?

Thanks
