How do I scan a ordinary photograph to send as attachment by email? I don't mean from a digital camera.Thank

You need a "Scanner"... You can also use MFDs (Multi Function Device) which integrates Scanner, Printer & Copier. You can use these devices along with some photo editing software which acquires images from Scanner. For example, Photoshop, CorelDRAW, etc.,

You need a scanner to do this; any sort of document scanner, or "all-in-one" printer/scanner/copier/fax machine should do this. If you don't have one yourself (and from your question I presume you don't), then you need to take it to a place like Kinko's, Staples, etc.; they usually have a service that can scan the picture for you, and convert it to a digital file. Once you have it in digital form, you can save it to your computer, and attach it to mail.

Obviously, you have to scan it, and I'm assuming you know how to use your scanner -- and that you have one. I usually will change the photo resolution through Adobe Photoshop to email pictures so that they are not so big. You attach the jpeg to the email that you're sending.
