        "description"   : "Some description of your badge",

        "howto"         : "To unlock this badge, you need to do something.",



        // The alias of the badge.

        "alias"         : "motorist",



        // The extension for this badge.

        "extension"     : "com_easysocial",

Hello Andrew McDonald,

Thanks for take your time attached this information to us,
I have tried to copy this and save in test.badge format in my locally

        // The default avatar for this rule. Relative to the site's document root a.k.a (JPATH_ROOT)

        "avatar"        : "media/com_easysocial/badges/socializer.png",

//Replace with my image png file

        // The default avatar for this rule. Relative to the site's document root a.k.a (JPATH_ROOT)

        "avatar"        : "media/com_easysocial/badges/test.png",

After i done this, then i tried to upload/install from EasySocial > Badge > Install > Browse the file "test.badge" and install, then everything is working fine.
I'm suspected that you're using the same image with other badge image file name, then causing this.
