Does re-sizing an image to a small size dynamically, reduce download time?

[fran7]

Hi, I have a general point of interest.

If one dynamically re-sizes a large pic on the way from a database to the browser and reduces its size, with an asp script, is the download equivelant to the original in byte size, or is the download time actually reduced?

Thanks for any pointers

Image size in bytes is directly dependent upon the amount of pixels within the image. So indrectly, yes it does. It reduces download time by the user since smaller image dimensions have less pixels. The same is true if you were to keep the current dimensions but reduce the image's quality.

Sincerely,

Although it might save download time, it will significantly increase server use, unless you are doing the resize one time only for each image. How are you modifying the image?
