$30 to own the movie is valid, but for $5 less, you’re only allowed 1 watch within 24 hours of starting. Something like that shouldn’t be basically the same price as the movie. With pricing like this, they basically force you to spend the extra $5. There isn’t even a point to rent the movie and they know that.
If you’re talking about Lemmy, it depends on what you’re using to browse. I use boost and for images like that, at the top right of when I have the image open there is a “HD” button which loads the image in full quality. Take a look around the UI when looking at an image, you may be able to find a button like that. Another option is to go into settings and look for an option to always load images in the best quality, that would also probably help.
Good luck 😊
