Yahoo/Google changed my description. why?

Why has SE changed my description when site stays unchanged?

[johnbug]

Hi all,
My website is a ecommerce site designed using fireworks (so everything loads as image, not text). I know this is not the right thing but the result looks better.
Here's the problem:

Because my site is image I was told to write description as meta tags, keyword tags.

index title: [snip]
meta tag, keywords: [snip]

If you search for [snip] you can find my site, and it says underneath as description: [snip]

BUT, if you search [snip], then my site will not be found, why is this?

It seems that only the title of my index is been searched, so I made my title, [snip]. This was perfect I was now been found easily.

I have 3 other sites [snip] that I started a long time before this one so I gave the new site a link from each of them. I got top 4 on yahoo/google UK when searching for [snip], and number 2 when searching for [snip]...VERY happy! (I am a one-man, part-time company).

But the BIG problem is yahoo/google have now changed my title from [snip] to [snip]. So this means I am now back at square one, my site can not be found unless you type [snip]!? My site hasn't been changed, just the description on SE.

So, what can I do to solve this problem without redesigning my whole site?

VERY sorry for the long message, just want to make sure everything is explained nice and clear.
