Interesting concept that I had not considered. My 10+ years of software development have been in GUI development, not web, so more complex things such as you suggest will require a bit more explaining to me;) First, though, I am using a reverse proxy server so that the downsizing only happens once, which works well with the PHP code.
Ok, this is what I am doing now: 1: the html page with all the image links is returned the the browser 2: the browser requests all the images 3: the server processes the request and returns the image It sound to me like you are suggesting that rather then #3, the server add the request to the queue and return a ???? (I don't know). Once the server is done down sizing the image it some how tells the web browser it is done. Correct? Sam On 3/26/07, Issac Goldstand <[EMAIL PROTECTED]> wrote:
Are the resized images needed *immediately*? Could you set up a seperate process to downsize the images one at a time, and let Apache/PHP/whomever just add the images to the queue? That way, the requests get processed much faster and you're also guaranteed not to blow the server's resources with too many concurrent requests all downsizing images at the same time.
