You mean in terms of applying a limited colour palette (say 32 instead of 256)?
Decreasing your colour palette basically just gives your graphics tool less to work with in anti aliasing your image, by denying it the scope to include those transitional colours. That's a different thing to compression artefacting though, which will tend to 'muddy' your image, rather than hardening and sharpening it.
Only annoying thing, is that FF likes to leave a little dotted line box round an image you've just clicked on. Dunno why. Mind, the rollovers aren't linked yet, so maybe that's why.
The dotted box indicates focus. It's very important for many users, such as those who can't use a mouse. Don't be tempted to get rid of it.
Hello Martin, long time no see 
Actually I think that simon is right, albeit that it's not usually referred to as aliasing in this context.
I think the blurring is an artefact caused because the frequency of the sampling used by the JPG compression is lower than the frequency of the original image.
In other words if the JPG compression squares were small enough (i.e. high frequency enough) then the blurring would disappear - but the file size would increase.

Oh right, I see. Like if you're using a touch-screen or something? Or navigating using arrow keys? I woon't know how to get rid of it anyway, tbh.
Rollovers are working beautifully. Had a bit of mild panic, as I'd forgotten the address of the site, so coon't access it, but all calmed down now. Just got to work out why one of the pages won't align to centre, only in IE Windoze...
RudeBoy: you can get rid of the focus box by doing something like:
a.rudeboyimagelink {
outline: none;
}
in your CSS.
Like this Tom?
STW in MSIE4.01:

Still usable, just not pretty!

The "proper" way to align to center is to set the left and right margin to auto in the CSS.
e.g.
<div style="margin:0 auto;">
blah balh
</div>
Make sure you are in "Standards Compliant Mode" in IE or you'll get all kind of weird rendering behaviour that is different from Firefox.

Well if that's the case Graham, then Simon's definition of aliasing and Bez's definition of compression artefacting are basically the same thing, and we're all just talking at crossed purposes. I think Bez's original point, about using the appropriate file format for the job, still stands though.
Hi Bez, how's tricks?

Agreed and agreed.
RB you had no idea what a can of worms you were spilling did you ?

Seat-of-the-pants web design, a la Rudeboy...

more like "clueless numpty-boy" :o)
Heh! I think SFB has it to a tee! It's on a testing server, so strings of numbers, rather than easy to remember names. Silly Billy here forgot to make a note of the addy... 
As for 'can of worms', well, my two can't agree, so I woon't expect people on here to!
Hi Bez, how's tricks?
Good, ta. Waiting to see what you boys are planning to follow the Wight Diamond with

Yes, we're waiting to see that too...
