Hi,
The display problem is due to insertion of the pictures sequentially with no supporting / defining structure. In the absence of structure, browsers will sometimes render differently.
I can see they were inserted after the text in your description. A simple HTML return code <BR /> inserted between each should make them vertical. Two such codes <BR /><BR /> would add separation in the display. If you want them centered, add HTML code <CENTER> to the front and </CENTER> to the end of the string of images.
