adding an image-banner next to gallery-name

[MikeNL]

Hi,
I am very pleased with coppermine. It just does, what I want. Thank you so much!

Now I want to change something. I use the transmission theme (where no image-option is included next to the gallery-name, I guess?).
I would like to have a banner (a logo of mine) in the same line as the gallery-name at the top of each page. I probably would have to change something in the template.html, but I don't know where exactly and how.
To be specific, - I want this logo to be in the same line or tablecell, where the gallery-name is shown. The gallery-name is aligned to the left and I want the logo be aligned to the right.
What exactly (in a code-example, if possible) do I have to do, to accomplish that?? And where in the coppermine-folder does the logo have to be located?

Thank you in advance for your quick help!
