I wanna make a lesson about harmonics of diffrent kinds, how they work, and how to performe them...

The problem is that i dont see anywhere i can add pictures and stuff, maybe sound clips and videos.

Is it possible to do that when you make lessons here on this site?

And if not, can i make a thred on the forum with the pictures i need and make a link from the lesson? and if i can, which forum would that be in? couse theres not supposed to be any disscusion in the thred.
I already got the picture, just wondering how to post them in lessons.

But just forget it. I made a thred with the pic there, and a link from the lesson to the thred.
