You can try using WinZip to compress the file.
I don't know if you ever use Microsoft Outlook, but when I send photos, there's a pop up asking me if I'd like to resize the picture or keep the original size before sending it out. It turned my 3.67MB picture to a 27kb.
If you want and trust me, you could email me and I could compress them through my Microsoft Outlook and send them to you.
