If I have an image that is 1024x768 and weighs in at 200KB, if I resize it down to 512x384 how big is the file that is transfered to the browser? Does the server resize the image and only send a small file to the browser, or is the entire file sent to the browser and resized by the browser?
Sorry to let you know but the file has to be resized outside of the browser in a graphics program. If you change the size of the picture in the html code then it still weighs in at the same size the browser just displays it in a I guess you could say "zoomed out" view.
