Photos not always sharp

I always upload photos for a post in 800×600 format. I have the idea that when the photos are visible on the site, they are no longer as sharp.

Could it be that the theme crops the photos, causing a loss of quality? What dimensions should I choose for my theme?

Hi Bettina,

This is about a header image but I am talking about the featured image of a post. If I turn on the option as described in the other topic, I get a different layout of the website with more space and that is not the intention.

Hi Bettina,

Since then, I’ve been uploading all images in 1920×1080 resolution, but the quality is still poor, even though the images are fully visible when you click on them and the lightbox opens.

Do you have any further suggestions?

Hi Calin,

I’ve since solved the problem myself. I changed the featured image size from the default (696×0) to 1068×580. This immediately resulted in a sharper image. However, I could literally see the difference. We use 1920×1080 images by default, but if you set them to the default size, they become grainy and blurry.

One other thing: in the documentation, I see that if you want to use the TagDiv slide gallery, you have to insert it via the classic editor. I find this very convenient, and I’d like to see (and many others agree) that the slide gallery is also available when using Gutenberg. Could you implement this in an update?
