People receiving mail from me can't download JPEGs
Just as the title says. If I send someone an email from MacMail, the receiver can see the jpeg attachments, but not download, or actually take them out of the mail itself. PDFs, and every other format seems to work fine. So I have to .zip every jpeg and some people, believe it or not, don't know what to do with .zips and then ask for a JPEG again.
I have left Mail and it's preferences completely stock, no tweaking of anything. This is not a new problem. It's been like this even with Leopard, and now Snow Leopard.
99% of the people I send to are on windows pcs, if that matters.
