Press F12 to open the developer console of your browser so you can follow up the image path which seems to be corrupted due to misconfigured web.config/.htaccess.
Could you show us your web.config/.htaccess file, the output of the developer console as screenshot and tell us in which directory your gamedata resides?
Edit:
I see you are using Arcturus which has an internal badge generator, do you make use of it? If yes its possibly misconfigured client variables in external_variables and external_override_variables.
