A friend (we'll call him “Fred”) asked me to look at one of his pages. I soon regretted it, since, on a 28,800 baud modem, the page took ten minutes to download. When it finished, I scrolled through. It had about 2K worth of text, four medium-sized pictures, and ten thumbnail pictures of Fred's co-workers.
Why did it take so long to download? One of the thumbnails, being
actually being scaled down from 332 by 176, To add insult to injury,
Fred had saved these scanned photos as GIF files, which, as we know,
explodes their size. The picture mentioned above, for example, was 76K
bytes as a GIF; as a JPEG it would have taken about 20K.
In short, Fred had made every mistake we've been talking about so far. How on earth could Fred have missed this problem? Actually, several factors conspired to hide the problem from him.
This combination of circumstances kept Fred blissfully unaware that his single page was consuming far more disk space than it had to, and was downloading at the speed of cold molasses.
Don't let this happen to you!
