I never thank you for your answer so, here it is: thank you very much! =)

I have another question now. It is posible to remove the "Details" button (the i inside a circle) when you enter into an image folder?

Thank you very much for your time!

Yes, sure! I embedded filerun into an iframe in my band site to use it, mainly, as an image gallery. The problem is that when preview an image the black-transparent background is shown only into the iframe, resulting into a non very good looking way to display the picture into the overall design of the site, so I though that changing the opacity to a 100% and matching the site background color will solve the problem =)

Thank you very much for your answer! =)
