As of upgrading to wp 3.5 the get_avatar function started not pulling in my default backup image. This has worked for many years this way and curious to why it would stop. I am using the normal use of the function as this:
the $url value is the correct path to my default image found in my images folder in my theme.
echo get_avatar($author->user_email, $size = '50', $url);
I did a little digging into the image that was being put there that is "missing" and it looks like the url is using an image server on the wp.com domain (guessing somehting like akamai). Not sure why though since i have the image local and dont want to use this as the image hosting location.
image URL starts with: http://i1.wp.com/
I looked at the source code function in the pluggable.php file. Maybe it is something to do with the gravatar return? Maybe they are changing the image location to be on the server?
Any idea what is going on here? I see there are functions that can change the way that it works to exclude gravatar but would rather still have that functionality if i can.
