Hi
Open this file /templates/ja_diner/images/decor/decor_blue.png
Replace it with your logo png image with same name.
Or add this code in custom.css file and change the image path with your image
.acm-slideshow:before {
background-image: url(/templates/ja_diner/images/decor/decor_blue.png)!important;
}
