The Form shows an insecure sign in the browser

Acquire an SSL certificate for my website, the link to the page where I have a Jotform form, although I get https, I get the warning of not sure, how can I solve it?

SSL is completely installed, even the support tells me that this form has an insecurity, I must configure that form correctly or change it.

Thank you in advance for your help.

PD: A thousand apologies for my English, I use a translator.

I investigated the browser console for any error, I noticed the images you have uploaded were insecure and has http in the links. Please re-upload the image in the Form by removing the images and then using the links with https in it.

I re-uploaded the images in the cloned Form and it resolved the issue.

Here is the link of the cloned Form:
