hey dudi,

I've checked in your site, it seems like you set "Show Post Image Placeholder" to YES from "Agama" category backend post option setting, take a look of my screenshot below. (I already help you set back to `inherit` option, which mean that system will refer back this original option from backend > Easyblog > settings > layout > post options > show Post Image Placeholder)

After I set 'Inherit' option from the category > post option > save, then you have to clear your Joomla cache from backend, then under this `Agama` category post will not appear `Image placeholder` now, try take a look of this link. (Note : replace back to your domain name)

Hope this help.
