Thanks Mark, and others !
What I wanted to do was genererate the thumbnails at view time. That is loop
through a list of images (bloody large ones!) and produce a thumbnail
gallery on the fly for the visitor. The directory content changes every few
hours so I wanted to it at page view time rather than pre-gen a set of
pages.
