you need an upload link for that. go to a website like this: https://postimages.org/ and upload your picture. then copy the link (its a bit iffy since the website sometimes adds some shit or smth so you may need to cut or delete parts of the link if it doesn't work, but like obvious parts not some random stuff like if the link is B:https://...com+8 then you need to delete the B: and +8 part, just examples)
