I'm afraid that would quickly use up both the storage space for the hosting service, AND will make the pages extremely slow to load. If we're talking .tiff files, I have some that are in excess of 500MB in size, and even a couple that go into the GB range. NOT forum friendly. If I were you, and insist on using .tiff files, then I'd highly suggest using your own hosting service, and linking to the image files. That's why my gallery isn't full with images, because I upload to my server and link from there.
