Web Design How to Change images in Dreamweaver

I'm using the travel ( https://freewebsitetemplates.com/preview/travel/ )template and i want to change the image on the left as well as the image in the bg of the navigation at the top (ive created my images i want in PSCS2).

The yellow boxes are around the image and if deleted that it would delete the whole logo area and copyright area above and below.

Please help!

Also for the logo above the large image on the left i put my info there and then put my copyright info in the bottem area and for some reason it gets distored and the copyright goes right to the bottem and the heading goes over the large image slightly.

 

You would have to open the image in Photoshop and change the image to what you want...then save it as the same image.
