When byteserving a PDF 1.4 or 1.5 file from a web server and veiwing the PDF in a Web Browser with Acrobat 6, thumbnail images do not display (you'll see grey rectangles) regardless of whether or not the thumbnail image has been imbedded ahead of time. Some of this is understandable. If the thumbnail is being generating in Reader, client-side, one-the-fly, then it would need the full image data for a given page present on the client to render the thumbnail image. If the full image is on the web server, due to byteserving, the Reader program can't render a thumbnail. However, Acrobat could render thumbnails for those pages that have been downloaded and speculative downloading of other pages could be utilized so that thumbnails could be displayed to users as needed. As of the current release of Acrobat 6 and Reader 6, Adobe has appeared to take the lazy approach of simply turning off any thumbnail display for PDF files that are being byteserved. This has caused much frustration with my customers.
If anyone knows how to make thumbnails apear in a web browser while maintaining page-by-page PDF byteserving from a web server, please say so. It would be much appreciated.
