Flickr lightboxes not working

Hi, I'm really struggling to get the photo gallerys working on my site and it is the last thing I need to do before my site is ready to be published. I've loaded all my photo's into Flickr and arranged them into set's (I plan to have 3 different photo gallerys on the website). I've added the Flickr lightbox widget to the area I want it on my Yola site and filled in the details on the properties section but all I'm getting is random images (not my images). Can anyone help, am I going about it the right way or should I be using a different widget. I want it to display products i.e. one photo gallery for bridal gowns, one for bridesmaids gowns and one for sale items. I've made sure they are available for public use and I've arranged into sets named appropriately. Any advice, the tutorials are not helping as I feel I'm following the steps they outline.
