I am trying to: I have a cred from with radio button choices of images to choose from. Before updates, I was able to save images using <img src=""> tag on display text area and showed fine. After some time, the image was displaying <img src="\http:// "> to show broken images and after cred from update, <img src=""> tag is not saving anymore. The input fields for radio button on "Display text" only seem to save static text. I even tried manual generic radio fields with sample img tags but nothing shows. The value works and form submission and publish works just showing the images on front end when you are filling out the form.
Link to a page where the issue can be seen: frontend - hidden link , backend - hidden link
I expected to see: Image tag save on cred form on post field area under radio display text option so it displays on front end
Instead, I got: no image tag saving after clicking save form or save field group.
I tested and confirmed that using HTML elements in a label is not allowed (in a form, or when setting up the field in Types).
I did get it working with a generic field, though.
I see you have the same problem I initially did.
The JSON for the generic field has values wrapped in double-quotes. The src attribute in your img tag uses double quotes and so breaks the JSON format. Change the src attribute to use single quotes, I think that should fix the issue with generic fields.
