Picture from message to gallery
Hi Lenard, did you receive a picture message through MMS on your phone? If so, it should be downloaded automatically to a folder on your phone as soon as you open the message with that picture in it. If not, try to see if you have an option to save it while you have it open in the Messaging app. If it gets saved either automatically like I said or manually like I suggested, it should show up in the Gallery without you having to do anything else.
Hope I've helped.
