Just as a piece of advice: post online somewhere the actual page with graphics - there are free webhosts out there if you don't want people to know who you're working for.
There are sometimes interactions between various pieces (as in this case an img style in the separate stylesheet that conflicted with the img style you needed in the table) that can make tracking down a problem very difficult. The problem (especially with tables) isn't always where you think it is.
But I'm glad it got sorted out.
