Why is the thumbnail pic not the first image from my hub?Why is the thumbnail pic not the first image from my hub?
Usually, we use the first image from your hub as the thumbnail picture which is displayed next to the hub title. However, an image has to be at least 80 pixels high and 80 pixels wide before it will be used as the thumbnail. If the first image does not meet these requirements, we revert to the second image, and so on. If you have no eligible photos in your hub, the thumbnail will automatically be set to your profile picture.
