How do I add an image to my topic or reply on JDFB Insider?

If you want to include a diagram in your post, you have the option to 'Add Attachment' at the bottom of any new topic or reply. 

You can draw it up in your own playmaker program and screen capture. I usually draw my images up in CoachMe Football and then share the image to my dropbox folder before I upload it. That's just me. 

You could do the same thing by drawing it on a piece of paper, taking a picture with your phone, and sending it to your dropbox. Then you can upload from the 'Add Attachment' link.
