detail page image slider at mobile devices

Hello,

I have been playing with my site in mobile device and I figure out that images at detail page slider doesn’t scale to the same height like in desktop size pages.

For example here http://www.informeron.lv/kur-paest/riga/restorani/darzs/
slider shows all images in same height in desktop size browser window, but if you change the size of your browser window to the mobile size you will see that pictures have the different height, and it doesn’t look good. Could you help me to fix it.

Thanks,
Dmitri
