Portfolio

I'd like my images to appear larger on the screen when one clicks on them from the grid. I'm using the portfolio template, and couldn't achieve the result by playing with any of the template edit sliders. The images themselves are quite large (2000x long edge) and opening them in a new tab shows them much larger than they are on the entry page. I also tried uploading full-resolution 6000x4000 images and their size did not change. Thanks

I'm not sure if either are possible, but here goes: When I click into a tagged set of pictures, could it just go straight to the full size of the first one? And then, when you're viewing a tagged set, can it not have navigation back to any images not using that tag? What I'm trying to do, as I remember indexhibit working, is to use tags to create static finished sets of pictures, and then anything not tagged goes under Posts as the main feed. But I don't want picture navigation between the two, especially as there is no title showing what tag you're viewing.

Is there any way to not have the last row of images be larger than the rest? Happy to change code if you can point me in the right direction. You can see it in the example preview of the Portfolio template: https://preview-of-portfolio-on-bjorn.blot.im/
