Blog posts are usually displayed on a WordPress website either on the homepage or on a separate blog page if that’s been specified in the site’s setttings. WordPress also creates archive pages for categories and tags.
As a general rule, it’s a good idea to keep images as small as possible because loading large images will slow a site down.
About 10 months ago I wrote a blog post, “A Simple Page Layout with the WordPress Block Editor”, as an exercise to compare using just the block editor versus using the block editor plus one of a couple of plugins; Stackable and Kadence Blocks.
I decided to make a very brief video demonstrating some basic methods used when building a page with the WordPress block editor.
Some time ago, I wrote a blog post giving instructions for adding a row of image links to a WordPress website. The methods I described should still work, but now that the new WordPress block editor (a.k.a. “Gutenberg”) has been released, I would expect it to be easier to carry out this task without using the plugins I had looked at before.
