texte = Assuming you're simply doing a writefile of the uploaded form data, there's no reason that JPEG files would be any different. They should end up byte-for-byte identical to the source file you sent to the browser. No re-compression is done, it's a straight data transfer (unless your upload page specifically sends it through some form of image manipulation program).If you open both your original image from your client machine and the uploaded image from the server into your browser, they should be identical.- brianAt 12:45 PM 6/6/02, Brian Wachter wrote: >When uploading JPEG images via a browser upload, the uploaded image is >distorted/blurry.
