And that line would be… ?
Oh, uh, I’m just asking for a friend.
 
 
In Firefox, you can use the Stylish addon  to set a user-style. It’s also available for Chrome  but I haven’t tried it out personally.
NOTE:  I have found myself logged-out once or twice when installing or adjust user-styles. I then had to login again.
NOTE:  Instructions are from my Firefox run; I don’t know if Chrome is different.
Install, restart FF. 
Click the Stylish icon 
Write New Style 
For bbs.boingboing.net  
Enter the following style: 
 
@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain("bbs.boingboing.net") {
  img.avatar {
    border-radius: 0%;
  }
}
 
Once applied, your results should look something like this

              If “gently-rounded” corners are your thing, up the percentage from 0.
This is 10%:

              Have we all recovered from The Great Rounding?
             
            
               
               
               
            
            
           
          
            
            
              Yeah, I think we’ve all figured out how to work around it or make use of it.
             
            
               
               
               
            
            
           
          
            
            
              I may go back to the star version I was using for a bit…

              I’ve got squares at work, but haven’t been bothered to replicate at home.
In general, I’m a fan of giving users more control over images – self-crop, etc. And cutting off the perfectly-good corners when there is no packing-algorithm to jam the circles together seems prideful without offering any user benefit.

              It also looks nice, I guess.

              I like this!  Want to set it up in Chrome, but I get an error:
  
What do you suggest?
             
            
               
               
               
            
            
           
          
            
            
              
Have major image bank search engines started offering a “search for perfectly circular images” option?

have we? 
 
 
Never bothered me; but then again, I specifically chose an avi which looks decent in almost any shaped thumbnail.
Doing some spring cleaning are ya, Jeff?

              That is so clearly a rectangle. I mean, I’m just sayin

              Maybe Quentin Tarantino didn’t know how to set up the aspect ratio on his monitor correctly.

I’m fine, thanks.
But just since you asked…at least several times a day, I grab someone’s avatar and pull it to the side, in order to see it as a square, to find out what got cut off.  (I may be kinda weird that way…)

              I prefer the square ones, but barely care enough about the issue to post about it.

              I can’t see it doing anything… just takes me to the BBS main page with no noticeable difference.  (Chrome Version 51.0.2704.79 m on Win10.)
