problem with a border in html

[I_M_Weasel]

I'm trying to apply a border to an image in html, I was using a style sheet with border-right cccccc, 2px solid and that was ok, however my works internet system no longer allows the use of style sheets, Ive tried putting the style sheet formatting into the page but this applies the style to all images which is no good as half of the page is made by some one else and I can't change any of that code.
So I'm trying to find a way of doing:

td image with right border grey 2px solid left border white 2 px solid etc

Can anyone enlighten me?

Thanks if you can.

yes I know its bizarre, actualy I'm surprised we can use images.

I'm allowed to upload -

jpg
gif
pdf
doc

thats it.

It probably comes down to that, someone somewhere will have seen a style sheet and come to the conclusion that its potentially dangerous code.
