Background image theme cutting off the bottom peice of the image

Hi,

Just need a little help.

I have just configured ( well still tweaking it a lot ), but I have a background theme, and everytime I put an image to a “slider” it looks fine on the slider page in the admin portal -> but when i look at the live site, it cuts off most of the bottom part.

I insert the image as a featured image -> and it doesnt matter whether I select thumbnail or full view nor does it matter if I choose a different size image…it always displays the same – cuts off the bottom bit.

And I have used a different theme as well -> one with a slider on the home page -> when I insert images to the slider -> it also cuts off the images and doesnt really display properly.

It is a full image theme.
