As it happens, this is not true. The 1.2.3.4 is not approachable from the
internet. Meanwhile I have uploaded the content of the script to
<http://home.wanadoo.nl/b.de.zoete/_test/bmi.js.txt> and added
document.write(' to the first line, so it doesn't do anything.

On second thought: my guess is that comp.lang.javascript is probably a
better group, so follow-up set. Appologies for putting this in
ms-windows.misc, if that was not appropriate.

No more mysteries. The javascript is a utility for surfing with UMTS from
Vodafone. It is meant to compress images and data (by deleting white
space).

i also use vodafone umts and i'm not very happy about this lossy
'compression feature'. espacially during presentations it's not very
nice to press always a key combination according
"Shift+R improves the quality of this image.
CTRL+F5 reloads the whole page."
to get the real content. vodafone isn't able to / won't deactivate it.
so i have to do it myself. i studied the script bmi.js and found out
that it appends the string "bmi_orig_img" to images for the uncomressed
ones. that means there is a transparent proxy in the vodafone net which
filters all jpeg and gif images from a port 80 (http) (maybe some other
ports too: 8080, etc.) and compresses it with a data lossy encoding. :(
the script changes the url of the image to get the uncompressed version.
if the user presses a key combination (s.a.) for example the url
http://foo.bar/images/img1.jpeg
changes to
http://foo.bar/images/img1.jpeg/bmi_orig_img/img1.jpeg
and for images generted dynamically
http://foo.bar/file.php?image
changes to
http://foo.bar/file.php?image&bmi_orig_img=1
so, to get instantly the uncompressed images i have to change the html
source (according above) before loading the images. for example in a
local modified proxy or the browser.
any ideas how to do this?
thanks, jan
