How do I include pictures (either that have been saved on my computer, or that are from a webpage) in my post?
if you don't prefer to type the code you can simply find the image on the internet that you want to insert, right click on it, click on 'Copy Image Location'. Then in your comment place you cursor where you want to place the image and click on the 'Insert Image' icon (middle row, 2nd from the left). It will insert the code in your comment below, simply go to the code and click between the start and end code, then click 'Paste'.
You can then make sure you done it correctly by first clicking the 'Preview" button below, before you click 'Post'. Your comment will appear above you typed comment, look at it and if it is acceptable, go back down to your comment and click 'Post' or 'Save'.
Your comment will then post in the thread with the image.
