First of all do you have an account with IHub? If I remember correctly, you need one. The easiest way for me to post a picture is to have two screens up. The Ihub posting box and my picture (wherever it is). Then simply drag it into the box. I usually like to do it right from my email where I just sent the picture, because I know where it is. I click on my email, click on picture, then click download and then simply drag the downloaded box. Please excuse if this is a "duh" explanation. I personally need to be lead by the hand with anything new that has to do with my computer.
