Pinterest style portfolio page / scattered images with CSS

If it were 7.0 I could answer this now, because I already do this on my site using summary blocks. The closet thing to what you want is to add a gallery section to a portfolio page (could be a new portfolio page) set the layout to Grid:masonry, Full Bleed which sets different ratios, enable the lightbox function and each image will be clickable. You can also adjust the spacing between images. All those options on one little panel. 

Thanks @derricksrandomviews I tried that, it gives a clickable image but not an actual link to a new page like I need in the pic attached below.

Oh, well then use the clickthru Link option for each image. Click the little image icon to open the edit panel and edit each image. There is a link option which will allow you to click thru to anywhere, off site or on site. Just enter the url address  or search for the on site page go want to go to. 

Thanks @derricksrandomviews It's really as close as it gets via the gallery method. It's not bad but the link opening is a little clunky and I can see the differences of it not being an actual portfolio page. 

Thanks so much for your help, I'll hold on and see if anybody figured it out via CSS. Someone in a separate post suggeste something to do with Grid-column:span 2 and Grid-row-end:span 2 and autocolumn.
But not much else of the code pasted and not much room to pick the subject back up.
