Check if tinydb tag has a stored value

[Projeto_TCC (Jonathan Gilber)]

I’m making a profile screen, where the user can pick an image from the gallery and the image he chooses get store on tiny db, so far everything is working fine, but the preset image on the picker always gets grey if he didn’t choose any image yet, how can i check if the tinyDB tag has a value already? like if the tag isn’t empty = set image to stored one, else do nothing

Here are my blocks
