Looks like eithere the cache or the server compresses the Webpage before
transmitting it to your machine ("Content-Encoding: gzip"). Also,
the log you sent is the transfer of a html page ("Content-Type: text/html"),
not of one of the downloads of a broken picture. What I suspect from
your description is that pictures are transmitted with an incorrect
Content-Type.

What I'm not sure about right now is whether a "Follow TCP Stream" ->
[Save As] will create a file that contains the binary data correctly.
If so, you can save the trace to disk and delete everything up to
and including the first empty line (line 11) and the pipe the result into
gzip -d. If binary cannot be saved correctly, this might be a feature to
add to Ethereal, decoding of Data with Content-Encoding that does
compression is not.
