If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
The simplest thing to do is to upload your sunflower image into your file manager. Then, under your "Properties" on the right-hand side, scroll down until you see "favorite icon". Click on this and then pick your sunflower image. Then, click on "Update" and you should see it in your preview or published site. Be sure that your image is quite small.
