Those are both hyperlinks. A hyperlink is a word, phrase, or image that you can click on to jump to a new document or a new section within the current document. Hyperlinks are found in nearly all Web pages, allowing users to click their way from page to page. Text hyperlinks are often blue and underlined, but don't have to be. When you move the cursor over a hyperlink, whether it is text or an image, the arrow should change to a small hand pointing at the link. When you click it, a new page or place in the current page will open.
If you click on these hyperlinks, you get redirected https://prnt.sc/, an image hosting site. I can't inline the images as there isn't a direct link to the images; it's a string of base64 (the format that images are natively constructed in).
