Actually, there's a method, at least in Firefox, you can use to get the original size of the screenshot!
1. In the thread, right click and select page info. You should a see a list of links in the media tab. One of them should show an image of the screenshot that OP posted and, if there are any, the screenshots that others replied with.
2. Copy the link of the screenshot you want and paste it in a new tab. You should see the screenshot in its original size.
3. Right-click and save.
Using dekodomo's thread as an example: https://miiverse.nintendo.net/posts/AYMHAAACAAAYUKlCoSk_6w
One can use the above method to get the link for Lon'qu!Brady (https://d3esbfg30x759i.cloudfront.net/ss/zlCfzRQ2_AgSVAH7kW) and save it in its original size.
I'm not too familar with Chrome, but as far as I can tell, right-click and choose page source. Then, find "og:image" which should contain the cloudfront link. Copy and then paste it into a new tab so you can save it. For replies, Ctrl + F
and you find the screenshot's Cloudfront link so can paste into a new tab to save it. Alternatively, you can also search ".cloudfront.net" which should net you the same results.
