Problem with uploading the product at CodeCanyon

Hello, I have uploaded one product on CodeCanyon and it is live. However, when I provided them the images to show them underneath the content, they are coming in the screenshots. Anyone here can help me with that?

You have to create then item description and host any assets that you want to include there - anything you send to envato will only ever end up in the item preview

Would you please tell me how to host them there?

You need to host then either on your own server or any free image hosting site

Then use html to fill out the description including relevant links

Thank you. It worked.
