Why are my screeshots not showing up?

Posted a screenshot this morning here and worked fine. Tried to post three more this afternoon and they will not show. Same format, from same photo storage but no go.

I'll check into this and follow up shortly.  I have a couple things I want to fix before I get to this.  Thank you for reporting.

Thanks, something changed just recently here as I just posted screenshots the day before and they all showed but now, from the same photo storage with same code only the code shows and no picture. 

Here is an example screenshot from SmugMug photo storage that worked yesterday but not today.

The below image in my signature is from the same place with the same code and it works because I added before the changeover.
