Gif & jpg look different in browsers!

Question

I'm a Mac user. Is there a reason for using one over the
other? I started using gifs for all flat colour with white out text
images. I noticed that when I started placing full colour photos as
gifs it gave a 'posterised' effect so I kept all photos to jpgs.
Now I've noticed that in Safari, the jpgs all have a darker version
of the background colour which looks awful! This is the page (on
the rollovers of the thumbs)...

On that same link, I also notice that on a PC in IE7, some
strange alignments - The word 'portfolio' in the top nav is merely
another column but on a grab my Father sent me it's dropped down
and should be level.
Any help appreciated as always.

> but how have these parts of code got missed
Not knowing the history of these pages I would say it's a
combination of
using ImageReady/FW HTML, with uncertain editing and pasting
into code view,
alongside use of the Property inspector to achieve visual
display without
any attention to the underlying code. Unfortunately you are
being betrayed
by DMX which was not the brightest bulb on the string when it
comes to
Design view.

It would not be possible to get this without actually pasting
it into the
code. You spot it by looking at code view for YELLOW
blotches, or by
validating your pages. Such HTML willl not validate.

The images involved are likely not only tiny, but also
(probably)
redundantly mentioned in your other body tag's massive
preload.

pixels?
Yes, they are. But they are top AND bottom.

You are talking about nanoseconds here.

Nothing. it's deprecated in favor of CSS.

You have to export as a JPG against that same flat background
color.
