Re: Line Ghosts

Steven,

At first, I couldn't see what you were talking about, but that's probably
because my screen resolution is set so high (1600x1024). I did a screen
captur and zoomed in, though, and I think I see the problem. It's caused by
the fact the image is a JPG image. JPG, due to the way it compresses and
image, frequently leaves artifacts like this on continuous-tone images such
as line art or drawings. The only way to correct it is to redo the entire
image from scratch, chop out all the non-photographic elements (the tire
lifter and example photo), then save the rest as a GIF image, placing the
photographic elements in where you want them as JPG... Or you could redo the
who thing as save as PNG, but not all browsers support PNG yet, and PNGs can
be pretty big.

Email me offlist if you'd like more explanation of what I mean...

Good luck!
Kehvan
