Image Manipulation in PHP

[Anon]

Hey all, I'm looking for suggestions on the best way to approach image manipulation as in its display size in a browser.

I have created a DB to store the binary data for pictures, but I am wanting to scale them in browsers to fit in smaller resolutions, but without making the image look very distorted. The image will be shrunk, not enlarged.

the way I was thinking to do, would be to use php to SOMEHOW get the pixel Height and Width, and then scale to fit using html.

any other suggestions on how to go about this?

Paul,

First off, scaling using html is a bad idea. It's almost surely going to give you the same image degredation as physically resizing the image, plus the user needs to
download the full sized image (ie. slower load times). You're better off using the GD functions and header output to send the user an image resized to his/her resolution size. Secondly, PHP is a server-side technology. That means it can't tell you anything more about the client's environment than what's sent in the HTTP_REQUEST header. PHP doesn't know, and doesn't care, what resolution the client browser is running at. You'll need to use a client-side tech. like JavaScript to get that kind of info. HTH,

Cheers,
