I have a sales form...how can I add image to each product

I checked the last form you edited https://www.jotform.com/61575146867164 and confirmed you attempted to add images to your product listing. However, all the links you have added on each product were showing a 404 error from your website

e.g. http://lnrpublishing.com/lnr006007.png

You have 3 options to choose from when adding an image to your products - UPLOAD one, re-use an image that was RECENTLY USED, or you can ENTER A URL

From how I'm seeing it, you tried entering the URL but the URL you entered was pointing to a 404 page, thus explaining why the images aren't loading. To fix this, you have 2 options:

1. Just ensure you will be using a proper URL that points to the image

2. If you're not sure what URL to use, I highly recommend you just upload the images since it's more straight forward. And the advantage of this is that you can re-use the image (if needed) for other forms.

Hope this helped, if you have further questions, don't hesitate to ask.
