[PHP] PPTs and thumbnails

Dear Friends, Is it possible to retrieve the first slide from a presentation and display it as a thumbnail on my site. Users will upload ppt's which should be displayed in form of thumbnails on my site. On clicking a particular thumbnail the presentation (.ppt or .pps) file should be displayed.

[PHP] Generate Thumbnail gif's

Dear all, Is there any pre-written code available on the net to generate thumbnail images for a picture. I mean I send the path of the image and my PHP Script should be able to generate a gif file of size 100x71 or something like that. Thanks Regards, ___ PHPLover *
