Site linking not showing logo
Hi, I have a problem when linking my site, for example on Facebook.
When I post my website link onto a Facebook page etc, it doesnt show the main logo, instead it shows the image of a null/blank photo image(the image when a user doesnt upload a photo to an ad).
I do get a choice though, from 3 images, one being the above mentioned, the second being an ad banner, the third being the logo.
When other people who are not too clued up post the link, they wont select the right image(because they wont know).
Is there anyway to get the logo to show as the default image when linking the home page?
Im sure there is an easy fix that Ive over looked within the group.
Thanks
