Hey I just got a new scanner , a hp scanjet 3500c, so I am learning how to do this. I have scanned an xray and I would like to send it to someone. When I attach it in attachment, it says 455.9kb Is that too big to send to someone? I don't want to jam up somebody's mail, and I don't know much about scanning things myself..so I was hoping someone out there could give me a crash course in what size I should keep things under.
