How to get multiple logos?
 

I want to put a logo on the left side and the right side of the header, is there any way to do this?

add a new widget area to the header configuration with three cells, put text widgets in them all. In the right and left cells and put your image in, in the center put your header image

search the forums for specifics and examples, many people have asked this or a similar quetion

Or, create header images that include your logos. Finished result might look like a centred header image with logos either side, but can be one header.

I have no idea where to even begin with that

start by reading the on screen documentation in the 'Add new WIDGET AREAS' section
