If you want to delete pictures from text messages on your Android device, there are a few different ways to go about it. The first way is to go to the Messages app and select the picture you want to delete. Then, tap on the three lines in the top-left corner of the picture, and select Delete. If you want to delete all of your pictures from your Messages app, you can go to Settings > Apps > Messages and tap on Clear Data. This will remove all of your pictures from the Messages app, as well as any other data that was stored in it. ..
