I’ve created images in midjourney and upscale creatively before downloading them, when I preview the image it says it has 72DPI which I don’t believe is enough for printing although Tom has said in his videos that if you upscale creatively it will be good enough quality for resizing to any size. Do I need to do anything else to the image or is it actually ok for resizing and printing as it is?

Hi everyone, I have been downloading mockups from envato but everyone I have tried downloads as a jpg when I believe it needs to be a psd to use in bulkmockup, can anyone help me on how I can download in the correct format or if other mockup websites work better, thank you!
