Wow! I didn't know that either. I tend to open in Microsoft picture manager
and print a contact sheet from that. It has other options too but it uses a
printer wizard and is a bit primitive. However did you then need to cut out
all the thumbnails from the contact sheet from Bridge? If so wouldn't it be
quicker to create an action and batch process thumbnails to a separate file
in Photoshop?
I've been having my own problems with PDFs. I find changing the settings in
Acrobat Pro a pain. I have a cover I have to make from Photoshop, because I
am not au fait with Indesign and all I had to modify a complicated cover
design was a printer's PDF. It takes ages to lay out the contents text in
Photoshop. I have asked that a designer be paid to design a new cover that I
can more easily modify in Indesign, with a little training, because this way
is too hard. We also don't do line drawings anymore and it's getting harder
to find a black and white cover image each year. Colour printing now costs
no more too. So a new design based on cover photographs is needed.
The current design has an edging with tone and silhouetted beetles. At the
printer's request I expanded it by 3mm for trimming (this was a delicate
task). When I made a PDF of the first page in Photoshop it downsized it in
some way. When I printed it to a PDF after modifying the printing settings
it trimmed the 3mm off the edges. 
Most frustrating though was when I combined the front cover (generated in
Photoshop) with the inside text (generated from a Word document) the
resultant file was downsized again!
Can anyone offer advice as to the different ways of modifying PDF quality
settings in Adobe programs?
Thanks,
Geoff

Thank you all for this discussion! I didn't even know it applied to me until
yesterday when someone wanted
thumbnails of about 70 pieces of art. I had no idea that Bridge could
generate a contact sheet. I put all the art
in one big folder and then made 2 contact sheets--easy as pie! Thanks,
Bradley, for mentioning this aspect of Bridge.
I didn't even know it existed!

Take care,
Wendy
