Do not want attachments embedded - how do I fix this problem?!?!?!

Question

I frequently have to send attachments in my mail messages (jpegs, tiffs, eps). However, every time I send attachments in jpeg, eps and tiff formats the recipient cannot download them. They are either invisible or embedded in the message - which I do NOT want. The only attachments that my clients seem to NOT have problems with are pdf's. How do I fix this problem? For now, whenever I have to send attachments in those formats, I have to switch over to Entourage. It does not make sense that this is a problem, since most designers use macs and have to deal with graphics on a daily basis, I am stunned that Mac is having this issue. I cringe that I have to switch to a Microsoft product in order to send certain e-mails. HELP!!!

Maybe I can make a picture. I don't know if it's possible to send a screen shot in these discussions.
When I receive mail, there is no problem. Attachments that people send me show up in an attachment list at the top of their message, just like in Entourage. I can flip the triangle and see the list of file names in their attachments, and can drag from this list to the location where I want to put a copy of the file. The fact that the image itself shows up at the bottom of the message isn't a problem (and is sometimes a benefit).
But when sending mail, it is very hard for me to compose my message. I can't control the attachments, and can't review the names of the files that I have included just before hitting "send".
Here is the Entourage format, which is what I really want. There is a place to put the attachments where they are independent of the message. I can drag a new attachment to this list any time while writing my message.
