I am having similar issues with jpg attachments.
How do I know what my @blackberry.net email address is?
Where do I go to set this up?

As a workaround, send the JPG file to your @blackberry.net email address instead of your BES email address. You should still be able to view it that way. (For best results, make sure you have OS4, although the interim OS3.8 might work)
