I don't know if this will help but here is how I put 2 pics side by side: I either size them to 400 width before entering or edit after. I insert 1 pic, hit the space bat once or twice and then enter the 2nd pic. I I want to do 2 more, I then hit enter which spaces me down and then I repeat. You can use this same method if you want 3 in a row, you just have to size them smaller. I try to keep the total width not much over 800 so you don't have to scroll on the listing. No HTML needed for this method. HTH
