If you're just using plain HTML, you can host your images on devianart and just add them as src in an image tag. Go to one of the images on your devianart gallery, right click the image and open image in new tab (so you see only the image, not the rest of the devianart page). Then use that as the src link.
For example, this page - Luna by AIGiantess on DeviantArt , open image in new tab gives us this link - luna_by_aigiantess_dfz4jw4-414w-2x.jpg (828×1242) (wixmp.com) . Now you can use the full url to display in your html project like this :
You can add height or width directly in the <img/> tag, or style with .css
