Strange images behaviour in property view

I am still testing the extension and template OSP Real Estate. Not sure if it comes from template or component. Once someone view s images - then the display is something like image attached. To check I went to the demo version and it is exactly the same. See the image.

Ok, it does not happen very often....only when someone views a slide show of images and click accidentally by second image (bottom one) That image is then enlarged.

Anyhow if you guys find the solution for this would be awesome.
