JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
The issue is still in our nice to do feature list. Since the issue is already been forwarded to our development team, you'll be notified once it is implemented.
At the moment, the images are directly linked with JotForm URL in the source code of html file so that the images are shown normally.
Hope this information helps!
