IE6 continually loading images when should be cached?

[Guest]

Help please!

Here’s the problem.

I develop sites for clients and recently did one that uses an image-swapping
javascript function to effectively animate images by swapping them. These are
..png’s. The page in question works great with Firefox and Safari, but with
IE6 I find that the images are being continually downloaded when I would have
though they should have been cached as I do preload them with js. This may
just be a problem with my own IE 6 and I am in the process of re-installing
and brining it up to SP2 under XP, but I don’t think so.

To see the problem please take a look at:

-- and tell me whether you still see IE looping file downloads in its status
bar? This should not happen and doesn’t on every other browser I’ve used for
testing, but if you do see the problem are their any pointers/issues anyone
is aware of and possible workarounds to what its doing? As I said I only see
this on IE 6. If you have Firefox around you’ll see it does the job properly
and the animations kick off and work fine without trying to continually do
repetitive downloads of the same small image files! Ditto for Safari on a
Mac. Thanks one and all!

Hi CR,

I don't know why but I have noticed that IE seems to always 'go busy' (the
throbber animates) on mouseover image swaps. Perhaps something to do with
the cache page expiry date?

Apart from that IE6 does not support png transparency. (comming in IE7)

Regards.

Yeah thanks for that! I fixed up the png problem using a small .gif and some
more js! But the issue I talked about on my orginal post is really
frustrating as it chews bandwidth! Its not just IE going busy it also just
keeps downloading the same 12 small images when it doesn't need to! I'll
check ou the cache expiry stuff but unless its a few microseconds it cant be
the problem!
