No, it creates one long row that will wrap based on the width of the browser window or perhaps a container DIV, using display:inline.
.thumbnail { * display:inline; * margin:10px; }
Or perhaps you need to set the columns and rows per page view? If so, I
would still use CSS for layout and limit the thumbnail count in XSL. You
just need to know the number of thumbnails (and which ones) to show and set
a class on a DIV that wraps all thumbnails to certain width to get the
correct number of cols and rows.
Ah, gotcha. Clever :)
