So, I've been on this site for a while, and I still don't completely know how this works.  Is there any way for me to post images in a forum post without including a source and using the (rather confusing, at least to me) insert/edit image tool?  Or is there some way just to link directly to the image through DDB itself if I'm using a map from a published campaign I own digitally?

The insert image tool seems confusing, but you just need to paste the URL and click ok.

Got it.  Is there any way to insert images if you don't have a link?

And is there any way to get links for the images in the digital adventures on DDB?  I can't seem find a link for any of them, and opening the link in a new tab just opens the adventure.

You should be able to right click and select "open image in new tab" that should be a page with just the image and the URL should end in an image file type (.Jpeg, .gif, .png, etc).

See, for whatever reason that wasn't an option.  Just "Open Link in New Tab," no image.

Never mind, figured it out.  I was opening the image first instead of just clicking on it straight from the page.  Thanks for your help!
