How can I take a pic of a pill so it can be identified?

I believe you do not have an imprint of your pill, in that case read the following from Drugs.com:

All prescription and over-the-counter (OTC) drugs in the U.S. are required by the FDA to have an imprint code. If your pill has no imprint it could be a vitamin, diet, herbal, or energy pill, or an illicit or foreign drug. It is not possible to accurately identify a pill online without an imprint code.
