A table cell background? Are the lines meant to be visible or not? Can you send me the original HTML and image files? The fixed point one obviously looks better in the animations, although, the small red squares get bigger and smaller as it zooms in. Michael -- Michael Drake (tlsa) http://www.netsurf-browser.org/
