help, i don't know the policy in posting pictures in mylot.

The policy Guidelines are here: http://www.mylot.com/o/photoguidelines.aspx You will earn for photos added to illustrate a discussion (and, when you reach a User Rating of 500, photos added to responses and comments as well) and for photos added to illustrate an Interest category. You DON'T earn for photos which you post to your profile. There's more information here: http://www.mylot.com/o/faq/faq10.aspx
