Low res pictures - when do they load?

I have some animated graphics that will be relatively
slow to download. I understand under picture properties,
you can specify a low res graphic which loads first.

When does it then load the normal graphic, will it load
the whole page including the low res graphic, then go
back and do the larger graphic?

or will it end up doing more work (low res graphc, then
normal graphic) before moving on to other things on the
page? - if this is the case it will not be a good
experience for my users!
thanks

Chris

On those browsers/platforms that support it, it's the first image to be
fetched, but in my opinion you get so much more bang for your buck by just
optimizing your page/images well and thoroughly, that it's not worth the
partial support hassle to use.

Thanks Murray,

Do you know the order graphics are loaded after the low-
res is loaded first?

If I have 6 graphics on a page, the 3rd is animated, I'm
considering loading a non-animated version as low-res.

What I'm trying to achieve is that all 6 images load
before the animated version is loaded. I don't want
graphic 3 to load its non animated version, then its
animated version, while graphics 4, 5 and 6 are still
empty?

regards

All files are fetched from the server in the order in which they are
encountered as the client browser parses the page from <html> to </html>.
Just because file A is fetched before file B is no guarantee that it will
also appear on the page before file B. The order of appearance of images on
the page is dependent on a) image size, b) network congestion/lost packets,
and c) the order in which the image is mentioned in the code.

I would not consider using a low-res image for the animation. In the case
that you describe, I would load a BLANK image for the animation, and then
swap that blank with the animated graphic with an onLoad image swap for the
body tag.
