This is a screenshot from an inactive MySpace. You can flip through these albums by hovering over them with the cursor. Is there a WordPress plugin that would allow me to do this or something similar?

I tried setting the query loop to "custom" instead of "default" and then changing these things that way, but that made all the posts show up in every category so I changed it back to "default." Pls help, TIA :)

I have a categories list on my homepage, but for some reason all of my posts are showing up in all of the categories. There is only supposed to be one post in the "Other Posts" category. I only checked one category for each and idk what is happening. Pls help, TIA. 🙏
