Any HTML 4.0 compliant browser should be able to see it. I believe it works in IE, Netscape and Opera. You would want to use simple graphics though because they will be cropped to fit the cells and text doesn't look good on garish backgrounds.

the only problems i've encountered is if i try to define a background image in the <table>. netscape renders the background image as if it were defined in the <td> rather than the <table>.
if you want to have a single background image in one cell, this problem shouldn't concern you.
but if you want to have a single background image span several cells in a table, you will have a problem.
