Brilliant! No I have not thought of that but now I will do it always! The short slug makes a huge difference and mondayred does nothing but add confusion lol.
Your other thumbnails show - maybe try copying the canva file and re-exporting the jpeg. I've had glitches with it a few times - always my fault as I investigate :)
I just moved the YouTube into the first position. Downloaded it 4 different ways. So frustrating. Basically, I can't do a graphic in the thumbnail until I have found a different program
Yikes! What are you downloading to? Can you email it to yourself direct from canva? Feel free to email it to me if you want to try that lol.
I've had troubles, but I always got something I can use. The You tube thumbnail looks fine though so don't worry - put your graphic back below somewhere and it will not matter if it is a jpg or png.
I also tried this - only having one canva graphic in the file. So I don't have to choose to export only page 1 because there is only one page. I can't remember why I had to do that for someplace once but it worked.
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.
