 +=====How to view the picture=====
 +Depending on your computing setup, choose the most practical means of viewing your program's image output:
 +
 +====Raspberry Pi desktop====
 +You've got a monitor and keyboard hooked up to your pi that you are using (preferred method for class).
 +
 +Open a file browser, web browser, or image viewer and navigate to/open up your **cos0.png** image in your **~/src/desig/cos0/** directory.
 +
 +Rinse and repeat as you go through revisions.
 +
 +====Raspberry Pi command-line via SSH/MOSH====
 +You don't have a monitor, so you are logging into your pi remotely (doable, and good intra-system practice)
 +
 +We start by running a successfully-compiled **cos0**:
 +
 +<cli>
 +yourpi:~/src/desig/cos0$ ./cos0
 +</cli>
 +
 +... which will produce an image (**cos0.png**); You want to put this in your web space (with the proper permissions set), so you can view it in a web browser:
 +
 +<cli>
 +yourpi:~/src/desig/cos0$ scp lob0.png yourusername@lab46.g7n.org:public_html/
 +</cli>
 +
 +Note that you will be prompted for your lab46 password.
 +
 +Then over on lab46, run this:
 +
 +<cli>
 +lab46:~$ chmod 0644 ~/public_html/cos0.png
 +</cli>
 +
 +Then, point a web browser at the following URL:
 +
 +  * https://lab46.g7n.org/~yourusername/con0.png
 +
 +NOTE: sometimes the web browser caches previous results, you may have to refresh a few times on revisions to get changes to manifest.
