title: Dynamically resize large image to thumbnail in PHP?
body: <p>What would be the best way to dynamically resize an image to thumbnail when a user requests a photo?   The images were uploaded already as jpgs that are hi res over 3MB?   I already know the file name from the database of which image they are requesting, example:   photo100.jpg, so creating a thumbnail in the php, then serving that newly created thumbnail t_photo100.jpg as a img src= would be ideal</p>
