Footer

Please I have a few questions:

– how do I get rid of the part of the footer in black intended for site titles?
– How do I add extra link in the footer (part in blue) , just next to the “copyright text”?

– How do I add widgets under the side bar intended for services. I have noticed that after putting services, there is too much space between that and the footer, how to manage that please.

– Finally if I want to put slide images that do not go over pages extremities limits, what should be the image size. I don’t want side images to full all the scree horizontally as it is the case now with the default dimension 1400 (horizontally). Please what should be the right dimension?

Thank you in advance
