Hi,
this is more oriented to the following settings:
Turn on the Avatars by the following settings
<!-- indicates if avatars are shown -->
<
add
key
=
"ShowBlogAvatars"
value
=
"true"
/>
Turn off gravatars with this setting
<!-- indicates if gravatars are shown -->
<
add
key
=
"ShowBlogGravatars"
value
=
"false"
/>
Leave this as is
<!-- Available values: identicon, monsterid, wavatar, full URL-encoded http address or virtual path of an image that should be served as a default image if there is no image for a particular address: http%3A%2F%2Fexample.com%2Fimages%2Fexample.jpg -->
<
add
key
=
"GravatarType"
value
=
"/App_Themes/Common/img/avatar_blank.jpg"
/>
Let me know if this is working now.
Regards
