Out of curiosity, are you really choosing games randomly? You must end up often on games that nobody remembers!

Regarding your edit, you can't do both. None of the lemmy UIs or apps make it clear, but it's URL or image, image takes priority, and then you can put whetever you want in the body text of the post.
No clue why it's not been made clear in any of the web uis or apps. I spend too much time here and see it multiple times a day.
About the edit at the bottom, unsure what you tried, but on Lemmy instances when creating posts, I'd presume you'd need to add the link in the URL field, and the image in the Image field.

This is a common mistake that and it's dumb that none of the UIs (or apparently any of the apps) make clear, but a post can only have an image or a link as its main thing and image takes priority, losing the link. They're mutually exclusive.
You can do whatever you want in the body text, having multiple images and links etc, but only one or the other for the "main post item".
OP needs to just put the link in the body text.
