I have not done much testing, but using a Windows machine at home,modem connection, and a couple of Navigator versions I was able to easilyupload image files to the server, process it with WebCat, then return theimage back to the browser -- just by selecting the local file in thebrowser and pushing the button. All the user sees are WebCat generated pages.From taking a quick look at your pages, I should mention that the method Ioutlined above makes use of WebCat's user/pass features so that onlyauthorized users can add or delete products and images, and only to theirown records. The product records for all the vendors are stored in one db. There is one record for each vendor in another db. When a product recordis created, a user id number (doing a lookup using [password] in thevendor db) is added. This way whenever I want to later display the imageit is simply /[user_id]/[sku].jpg (ie. /images/554/989855.jpg)If I were you, I would not show the sku in the record creation form,instead do it as a hidden value. For some ideas on how to do some of thesku, lookups, and image display WebDNA -- Ken did some great examples inthe classified templates of Typhoon.I hope that makes some sense to somebody else but me...
