Changing an image in a theme from gallery
I've have chosen a theme that I really like. (Construction category- dark blue on blue/ last theme in category)
I want to change the lower image that replicates the one under company name. I would like to keep it the same size,and simply replace it. It is covered by the dark blue box with some transparency...(I think)
How can I get the size of this image so I can save my image accordingly? How can I replace this image once I do that?
