another question according the 1.6 template:
Every time i try to use a png with a transparent background as a logo, the logo is displayed with a white background. Any suggestion?
Go to your back office > Preferences > Images
Scroll down to "IMAGES GENERATION OPTIONS" and set "Use PNG only if the base image is in PNG format." as you can see on the screenshot:
Now you can finally upload your logo in the back office. Click on "Preferences" in the menu and then "Themes".
At this moment you have to upload your logo again. Make sure you are uploading a transparent logo. In that case, it should be a .PNG picture or .GIF
