You can upload and store images in a Dabble application using the Attachments field type.
Alternatively, if your images are stored on a web server, you can use a web link field to write the web address of any image stored on an external web site. Simply type or paste the URL to the image into the field, and make sure Dabble knows to format it as an image by using the Field configuration and choosing Links are to images as a formatting option.
Regardless of whether an image is loaded externally or as an attachment, you will see the image while you are editing the entry and the image will be displayed as a thumbnail if it is a column displays the field in a Table view. Click the thumbnail to load the full image.
