Ayooo does anybody here knows how to put stamps? I tried using the same method I used for my art on my bio, but it didn't work :((

I'm new to this platform and couldn't find any tutorial so please bear with me ;;

--Update below--
No html code or anything is working for me for some odd reason? so like, I am still greatful for all the help but I don't think it'll be necessary no more, still thank you for your patience

--Update 2 below!--

I finally understood how to put them! my problem is that it wasn't taking the ones from Sheezy art but apperantly it does take the ones of other social medias like DA! (although I don't used it much bc of certain situation with their AI program)

Still ty everyone who bare with me and helped me!
