Thanks mattski and Andy

Yes - a .png file, but for some reason wouldn't paste in photoshop, irfanview, mspaint... and was missing when i tried to open it from photoship. The only thing in my images folder was that little orange gif that looks a bit like a tiny sun.

I worked out how to fix the logo by accident. You can save text as a gif if you right-click on it - it gives you the option to save it as a gif there. So I've done that.

Yes, I knew that 1024 width would cause scroll for someone viewing in 800 width - but I thought maybe I could put all the important info. plus the header/page graphics within the 800 width so that it looks 'right' and complete when the page is opened at 800.
Personally, I really dislike 800 width pages, and I know that some people who don't understand what they're at that width don't like them either - they feel squashy when you're used to a wider page. (personal view/experience only)

(thanks for the info. on robots.txt as well. I tried to do it, but vodahost was down for half an hour or so around that time - both c-panel & therefore my website)

Any other views welcome :)
