This is a tool for X/Twitter. You can add a nice gradient background to your images directly from the post. Just click the new image icon, load the image, and make your images more cachy with a gradient background without leaving X. Yo can use the BlueSky version here: https://chromewebstore.google.com/detail/bluesky-image-bg-framer/ebadbopjnnllkplbkebpndhenfaefodg
