Pls explain. I do not get your point.
I see it’s possible to generate squarred thumbnails, but not available for covers, so if I want to display squarred covers (for example with centered view, all in 200×200) made from horizontal and vertical photos, I need the smallest border to be at 200px. For the moment it’s allways the largest, so it could be useful to add a select-box in settings to choose which border is set to the size defined in 1.D.5. This example is for covers, but I see it’s the same empiric rule for thumbnails size.
Are you aware of the fact that you can force the height to be equal for all cover images? This is to prevent layout problems, i guess that is your point?
Tick Table I-D7: Size is height.
For ‘normal’ thumbnail displays you can select masonry style in Table IV-C3. Maybe you like that? (note there are 2 types of masonry style)
I see Table 1-D7, but for vertical images it will not fit the same width as horizontal images, so any background effect will look quite ugly.
I found a css solution for my customization, and I also discovered that Table 1-C2 “square clipped” has effect on my covers 😉
