Cheese
by taking a picture of your phone's screen with something else
It depends who is taking the picture... they will be trying to tell you something.
Taking a picture works. Taking a photograph also works.
Google it, something will come up
Find something you have in common and start from there.
You can probably Google that information, and find something.
I would recommend Digital Camcorder Cameras only if you are serious about taking pictures. If you are new to picture taking, purchasing something like this may be too advanced and purchasing a regular digital camera might be the better option.
There are some police officers that take picture of dead bodies. You will also find people working for coroners taking these pictures.
The text is important, the picture is just to grab your attention. Once someone's attention is placed on something they will read to find out what the picture is about.
Every picture is worth a thousand words, the picture could tell you something. This might sound crazy, but 'communicate" with it
Have one person driving another person taking the picture.
