How to hide the image subtitle in VirtueMart 3.0.6.2

[VMRESLO]

Hello everyone!

I have a problem with hiding image subtitles on the image slider in product details pages. The first image is perfect and does not show any subtitles, but all others do. I have tried hiding the class "fancybox-title-inside" in the jquery.fancybox-1.3.4.css but the empty space remains. On the backend in the Product images I have left empty the boxes Displayed image subtitle, Image Alt-Text and Image Class.

How can I fix this?

I am using VirtueMart 3.0.6.2 on joomla 3.4.1.

Thank you in advance!
