Hi there,
I am really sorry for the delay of this reply as we have been overwhelmed with the support recently since the release of easysocial 1.4.
Ah I see. It seems like you are using mighty sites extension and the photo are actually referred back to your original site which is jskill.com instead of hero.jskill.com. For example the following image url are accessible under jskill.com but not hero.jskill.com
http://jskill.com/media/com_easysocial/photos/40/49/lubu2_thumbnail.jpg .
To fix this, I've applied some temporary hack inside your /administrator/components/com_easysocial/tables/photos.php at line 1494 where it will use the domain from jskill.com instead of hero.jskill.com and it should be working fine for now. Please have a look.
