No. "IDs of categories" and "IDs of houses" are empty as default. I checked my page using firebug. It seems the code which points to the pictures are there (I paste part of it here):
<img style="height: 100%; width: 100%;" alt="img" src="aartaa.jireyeketab.com/./components/com_...6D00C921_4.jpg"
But they are somehow invisible (I don't know why). I hope you can help to solve the problem.
