Thanks for the responses folks.
Patr100 - cell padding and borders etc are all 0.
Taran - good to hear from you again. What you say sounds good but I dont really understand slicing. I have Fireworks so I guess I'll spend some time figuring this out.
When I do slice as you suggest, do I put each new slice into a seperate cell or all in the same cell?
Sorry to be thick - Paul
