I am making a small web site to post images onto. The images that I have are all over 1024x768 pixels in size. I want to make an index page with smaller versions of the images that the visitor can click on that will open up the larger images. What I am wondering about is displaying these thumbnail images. At first, I was just changing the width and height attributes in the <img> tag, but the image files were too big and the page took way too long to load. Is there any other way I can display thumbnails of an image without having to create a second, scaled-down version and saving it to the directory? Thanks for any help in advance.
