Set gravatar default image no from default?

[ipbfuck]

Hi,

maybe is already possible, but i don't have found this in acp...

atm gravatar, if enabled, is from default:

 

then, if user not set image (and not have gravatar registered) any empty avatar is serve by gravatar server:

eg:

link: https://i1.wp.com/laltroweb.it/uploads/set_resources_40/84c1e40ea0e759e3f1505eb1788ddf3c_default_photo.png?ssl=1

 

then, unuseful external request, when we already have same image in template with: {resource="default_photo.png" app="core" location="global"}

link: https://laltroweb.it/uploads/set_resources_40/84c1e40ea0e759e3f1505eb1788ddf3c_default_photo.png

 

then, same id in link: gravatar proxy image present in my hosting and i ask this image to gravatar... why i need this if i already have "defaultimage" in my host?

 

can be this fixed and set gravatar only by user setting?
