I figured it out! just couldn't think any more last night. If I upload it to igmur and use the markdown link from there - it works !! I was downloading it to my desktop, then ran it through Tiny - now, I have to add this extra step....
Just for the thumbnail. The other graphics show up fine in the text.
Learned something new!! yay!!
Oh that's great. I'm glad it worked. Yes, it is only the thumbnail that has ever been a problem for me.
