Hello,

As we have already mentioned in your previous ticket, in  order to be able to crop your image to various predefined dimensions for masonry,each image should be properly sized. Here are the border values for each cropping variant. So you need to upload images with this dimensions or above.

portfolio_masonry_regular - 500x500 px
portfolio_masonry_wide - 1000x500 px
portfolio_masonry_tall - 500x1000 px
portfolio_masonry_large - 1000x1000 px

Then you need manual to create this mosaic and to set right image to the right place.To have the similar layout like in the demo you listed - this 'mosaic' masonry requires carefully ordered portfolio thumbnails.

Please note that you can choose desired image size for each portfolio item >>

Also, you need to enable Fixed image proportions in Portfolio List settings.

For any other issue you are facing please feel free to ask us and we will assist you as soon as possible. I will give my best to help you building your site.

Thank you,
