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!
I have just tested adding an external link to an image and it worked for me. How are you adding the link to an image? I added it by putting the image on the page, click on the Properties Tab, click Choose a Link and then added an external url in this format: http://yola.com.
Can you give this a try and let me know where you are not able to proceed or what seems to happen.
