Trout, let me see if I can help.
Your links from Flickr look like this without spaces:
[ url= https://flic.kr/p/CFWPzN ][img ]https://farm5.staticflickr.com/4487/24080883108_644e821d63_z.jpg[ /img][/ url][ url=https://flic.kr/p/CFWPzN ]Steel Mill - 7/2017[ /url] by [ url=https://www.flickr.com/photos/4valhal/]4Valhal[ /url], on Flickr
Which turns in to this: Steel Mill - 7/2017
, on Flickr
All of your description text for the picture needs to be after that final [/ url] like where it says "on Flickr."
I think what you're doing is putting all your text inside the brackets to describe the pics which is making it all a link to the picture.
If I am wrong then my apologies.
Love the pics by the way. The candles add a creepy ambiance to the tunnel there. It sounds like a really cool tunnel to check out.
