Images doesn't save

I'm testing great component Os Property and I have a problem when i upload images in module, doesn't load. I check my php config and i have GD support.

GD Support enabled
GD Version bundled (2.1.0 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.3.11

I check permissions in /components/com_osproperty/images is set to 777.

I tried to install sample data, but doesn't work.

You can see it in www.sistemeslinux.es/index.php/component...r-zona-los-pinares-4

Thanks a lot.
