Problem with T-Mobile 3g & web images?

Hi all,

I am having problems today viewing websites through T-Mobile 3g (via an
N95).

For some reason images are not loading - or taking forever to load.
Things like Flash work fine and I can even open a VNC connection to
another computer which opens the page without a problem quicker than it
can be loaded locally.

It is perhaps relevant that this is the same setup in the same location
that I usually use without problems.

I assume this has something to do with the image downgrading which
operates when using the T-Mobile gateway so wondered:

1) Is anyone else having this problem?
2) Is there a way to bypass whatever proxy is filtering the images?

TIA
