That sounds right for pages that are primarily text, where the images
elements are decorateive elements, product id shots, etc. and particularly
in commercial venues. Where the true purpose IS the image, the image has
to contain enough information to be worth viewing. When I run across a
site of photos that are like big postage stamps, I think "Nothing to see
here." and move on.
I don't think your dial-up speed numbers 'add up'. I just used dial-up to
view a 256k image. Total time was under 17 sec from hitting return to
completion, with 5-6 sec. before the site started downloading the image.
Also, the site used progressive load, which should cost at least a sec or
2. That works out to something in the neighborhood of 25kbps net
throughput. Dial-up from here is seldom better than 35-38kb, so someone
with a 48kb connections like Mike has tonight, should get a net of about
30. Are you perhaps off by about 10x? Am I missing something?
At 30kbps, a 100k image should take about 3-4 sec. to download, which
seems quite acceptable to me. That gives room for both reasonable size and
high quality jpegs.
30 kbps is 30 kiloBITS per second, whereas a 100"k" image is 100
kiloBYTES. As you're all probably aware, a byte is eight times larger than
a bit. A 30 kbps throughput is actually delivering around 3.75 kByte/sec.
(assumes "perfect" throughput with no network overhead, an impossible
assumption in real life, but what the hey), so a 100K image should d/l in
about 27 seconds.
