How can I boot my raspberry pi 2 directly into displaying a graphical image? What needs to happen is once I plug it in it boots up and directly after it finishes it just displays an image without outside intervention. Is there a way to do this? Thanks in advance!

to execute commands "at boot", if autologin is enabled (since what it really does it execute them when the pi user logs in), i'd suggest editing the autostart file wich is in the ~/.config/lxsession/LXDE-pi/ directory.
just add these two lines at the end of the file:
@export DISPLAY=:0
@epiphany /path/to/your/file.png &
P.S. you need to have root permissions to edit autostart

"to execute commands at boot" -> The general form of this is actually a bad way to execute commands "at boot" unless autologin is enabled (since what it really does it execute them when the pi user logs in), and even then it should not be used generally for just anything. However, it is a decent way to do simple things with the GUI in that context, which gets complicated unless there is an autologin.– goldilocks ♦Apr 19, 2017 at 12:15

Yes, what I am saying is it will only work if autologin is enabled. If it isn't, then nothing will happen until someone actual logs in. The boot process does not normally log any one in, as it is not required. The autologin set-up on the Pi is unusual.– goldilocks ♦Apr 22, 2017 at 14:57
Note that there are many image viewers (e.g. fbi) which can render images directly, without the need to start an X server and boot into a desktop environment. If you need to save boot time and SD card space, you can run
fbi -T 1 -a picture.jpg
at boot time as described here.
