How do you post graphs, images, or scanned solutions in BlackBoard?
First you have to produce a graph or image in your computer (see Graph using an online grapher or simply draw by hand and scan in) and save it as a .gif or .jpg file (see Saving the graph via a screen print) or transfer the graph via cable from your graphing calculator (see manual). Then embed the image into your BB discussion board post (see How do I embed a graphic in a discussion board message in BB).
