Unable to add absolute link to an image

Hello, I add a link to an image by adding a link field type: url to image default.yml. Then I cannot put an absolute link, only links with beginning with http… Any idea why and how to have it work? Thank you
(if I change the url in the txt file I can put an almost absolute link, it doesn’t work like when I add a link from the panel, I have to add a level before the link /diana/link, /diana being the root of the site on localhost)

Why don’t you use a text field instead? You can give it an URL icon or whatever to make it look like a URL field if you want.

Yes now it seems evident, thank you.
