CellphoneGrayed out, or just lighter than normal?
I have never seen that happen.
the Picture Icon you want, has the shape of a Mountain Profile, just to the right of the Chain Line fence looking Icon.

The Pictures must be of a format that can be uploaded, jpeg, jpg, png
click on the Icon, and then click on the new popup, browse to the pictures and Double Click or highlight and click the OPEN button.
. I have to ask, are you using a Cellphone, or a PC ?
