You don't actually need all the extra 131 characters being pasted at the end of those Flickr URLs.
Instead of pasting this:
You can use:
https://www.flickr.com/photos/triborough/7332755116/
or you can use:
https://flic.kr/p/caYhCm - Which is available from the arrow icon in the bottom left of the picture.
It will take you to the exact same page.
The second (shorter) link is preferable because this is much easier to read in Source mode. The link after the /in/ is what flickr uses to track where links come from; photostreams, albums, faves, galleries or groups.
Someone else on the wiki wrote this, I couldn't say it any better.
