I have uploaded images to my form using the Upload field type. How can I refer this image in my HTML View?

The image/file URL which is stored via the file upload field will be in the format given below:

https://creatorexport.zoho.com/DownloadFile.do?filepath=/<FileUploadFieldName>&sharedBy=<userName>&appLinkName=<appName>&viewLinkName=<viewName>;

In your HTML view, you can generate the image URL of the above kind and display it in the HTML view. Below is the sample HTML that you can use in your HTML view.

<img src='https://creatorexport.zoho.com/DownloadFile.do?filepath=/<FileUploadFieldName>&sharedBy=<userName>&appLinkName=<appName&viewLinkName=<viewName>'>

To fetch the images from your form and insert it in your HTML view, you can use the fetch records task as shown in the format given below, where Input.ImageName is the parameter defined in the HTML view.

rec = Form [Image_Name = input.ImageName];
<img src='https://creatorexport.zoho.com/DownloadFile.do?filepath=/<%=rec.FileUpload%>&sharedBy=userName&appLinkName=app1&viewLinkName=view1'>
