Yes, but this solution requires hacking the plugin template. Bad idea! This should be included in the plugin.
I’m trying to do this also. Should I make this change inside image-widget.php or somewhere else? Line 12 of the newest widget does not have this same coding that Skivsamlaren’s link provides.
The widget.php that needs to be changed is found by going through your ftp via this route:
wp-content>plugins>image-widget>views>widget.php
and through the admin side via this route:
plugins>editor>image-widget>image-widget/views/widget.php
Little late to the party, but thought I’d add for other people that you can override this template in your own theme so as not to mess with the plugin. The instructions are in the readme.txt
