Logo not showing

I have managed to install the template and made the logo exactly the same dimensions as original logo, saved as png and uploaded into template images folder. It's visible in the dropdown box, but not showing on the web page when selected?

Am I missing something?

Make copy with name 0EPUKlogo.png

Thanks for your response ivan,

that did not work, neither did jpeg, neither did some of the other images I randomly selected from the drop down, but the original logo when selected appears.

Is there another folder where a copy needs to be kept?

I currently see logo with word "EDUCATION" ?

Yes we hard coded it with CSS mods.
