Pictures are so important now days. Thankfully, they are now so easy to take, save, send, download, upload, share, etc! When a picture is sent to your phone via text, you can open it, press on the picture, (or right next to the picture), until you get a pop-up that gives you the option to view slideshow, SAVE PICTURE, forward, view message details, delete message, or lock message. You can select Save Picture, then it will be saved to your Gallery. (Likely in the All Downloads file.)
I trust this is helpful.
