I only use Xara, and Painter for graphics so I am not familiar how other programs work. Do other programs tile or fill an object with a small bitmap repeating it to totally fill it?

The reason I am asking, is: I have explored some of the scrapbooking sites and lots of times they have fills to use as page backgrounds for download and when you do they are huge i.e. 3600 x3600 pix and over 2mb which bigger then the actual scrapbook page.

I create lots of seamless fills, and the maximum size I make is 300 x 300 pix and under 300k. If I offered some of my much smaller fills on a webpage for download would people using most other programs be able to use them as intended? Or is the problem the creators of those scrapbook sites just don't know what their programs can do?

I hope I made myself clear.
