SOLVED !!! no-image picture option

hello, does anybody know if there is an option to set a noimage picture for properties with no images? i mean i would like to choose an image to display in os_content_slider thumbs and in properties listing thumbs when a properties has no pictures.

i solved this, it is simple, just replace no-picture.jpg and nopropertyphoto.jpg in modules/os_content_slider/images with your own pictures....
