Good afternoon. As for the redirect url issue, i highly recommend putting:

var redirectUrl = "<?= get_redirect_url() ?>";

in the redirect, unless your wanting to push the user to your website instead of their intended destination.

I have an issue and feel a little silly not being able to find the answer anywhere. I am attempting to use custom images which i zip into the custom page, but no matter what i do, i cannot get them to show up on the custom page. Has anyone had any success in this, and if so, will you please share your code for achieving this?

Thank you very much in advance, and look forward to a long and good experience with Untangled!!
