I want to know where all these DIY guys get the software to draw such nice diagrams.

I dare say most are borrowed from PDFs and other sites. I've done a few on my own with photos and paintdotnet and it is tedious.

EDIT: Added link.

I try that, but it copies in an incorrect format, not JPG or PNG. I can't recall, but it doesn't let you post it after it is modified.

If you are using layers, you need to merge all the layers down (or delete them) and then save as the desired file type. Paint(dot)NET saves multilayer files as PDNs (proprietary?). I use .PNG for anything that might go on the web.
