When you create a new image you just choose Transparent in the dialog,
if you've already made it you can just select the area you want to be
transparent and cut it away or if the background is the only part of the
image using a specific colour then you shoudl be able to select it as
the transparent colour when you Export as a GIF.  The online help is
actually pretty good in Photoshop too if you get stuck.

Email a .JPG'd version of the scan Ben, to chris@berling.demon.co.uk,
I'll do it, return it and tell you how... bit hard to say without seeing it.

You can use the selection tools to select the logo, copy it, select new
document making sure backgroung is et to transparent in the new options
box, and that u r in RGB, then paste. You should have a transparent
background.. then save as a .PIC or .GIF file, or email it to me!

If you just need simple graphic operations you might be better off with
Graphic Coverter, shareware about �15 on most cover discs or at
http://www.lemkesoft.pingnet.de/   this has a transparent tool and is very
easy to use.

Many thanks to all the people who responded, in here and via email. I've
now been given about half a dozen different ways of doing it! :-)

Will try what seems like the easiest one on Monday.

Change the colour mode to indexed colour and choose the web palette
option. If it is all flat areas of colour then don't choose dither, if
it's got a lot of different tones then use the magic wand to select all
the areas you want to be transparent before you change to indexed
colour, choose the dithered web palette then fill the selection with a
colour that doesn't feature in the logo. Choose Gif89a export from the
export menu and use the dropper to select the transparency colour in the
preview. Then give the file a name and choose save.

I'm not sure how it will work in a persuasion presentation. You may need
to try an alternative method (EPS). Select the background using the
magic wand tool. Choose Similar in the selection menu (to ensure you
have all areas selected - not just ones that are next to each other).
When you have a selection open the paths palette and choose Make path
from selection to create a bezier curve path of your selection. When you
have a path choose clipping path and select the name of the path for the
clipping path. Save as Photoshop EPS and ensure that it says the name of
the path in the clipping path pop-up menu. 

Bear in mind that with both these types the original size is the size
that you will be stuck with so if there's loads of white space around
the logo then crop the image down using the crop tool. Hope this is of
some use to you.
