You can change the “Saga” icon image for any template. Download an image below, rename it to saga.png (or whatever your current them named it) and paste it into your C:\Program Files (x86)\yaDIS\templates\*yourcurrenttemplate*. This will overwrite your current saga image. Before you do this, rename the template’s default saga.png image if you want to keep it.
Clicking an image will open the slideshow. Right-click on image and “Save image as”.
