trying to figure out pictures so i can open up commissions here, but for some reason i can't figure out how to make them work. here's some of the codes i've tried (don't worry, i know to delete the asterisks, they're just there so you can see the codes themselves and not just broken links lol)

code: <*img src=https://imgur.com/a/pu59HAy>

code: <*img src="https://imgur.com/a/pu59HAy" width="400">

for clarity, the images i've been trying to use are hidden on the imgur site itself, but i tried making them public and redoing the code with fresh links and it made no difference. also tried a couple other sites to no avail. does anyone know what i'm doing wrong?
