How to work with the tools under the hotspot plugin settings.

The tools under the hotspot settings are made up of five sections: Content, Hotspot, Appearance, Colors, and Styles.

1) Content

The popup content section is where you can add content to the popup. You can embed various content types -- simple, HTML, Image-left, Image-top, video-top, image, video, audio, iframe, pano-link, link and title. Click on the content type under the popup content settings to select a content type for the hotspot.

The following is the brief information about the types of content under the popup content section.


Simple is a content category that includes a title and a short description. With the Simple Content type, you can put briefly the main information to help the visitors better understand the product, without opening a new tab to look for the information.


HTML content types include HTML code, which can be used to incorporate a webpage and its contents into a virtual tour. The HTML <img> tag will embed an image of a web page that is not only technically inserted into a virtual tour, but also linked to the web pages.


It allows you to create a Popup that contains an image/photo with a piece of brief information appended on the right side. Image-left content enables you to showcase a specific area or product details so the visitors will better understand the area or product.


Similar to Image-left content, the image-top also allows you to showcase a specific area or product details with a caption appended to the image.


It allows you to create a popup that contains a video with a description underneath. In general, visitors simply click on the hotspot to view a Youtube/Vimeo video that has the information related to the product.


Similar to Image-left and image-top content type, the image content also allows you to showcase a specific area or product image but without a caption.


Similar to video-top content, it allows you to create a Popup that contains a video but without a caption. You can insert a Youtube/Vimeo video to the hotspot content that has the information related to the product.


It allows you to attach an audio file to the hotspot that has the information related to the product. In brief, you can place your product audio into the virtual tour that makes your tour more appealing to consumers.


It embeds a webpage on the hotspot using the iframe code. Using Iframe content type, you can embed documents, videos, and interactive media within a virtual tour and the visitors can easily connect to a link that contains information about the product.

Link-pano allows you to join the previous and next panoramas in one tour using a hotspot so at the end your tour visitors can easily move from one area to another only by clicking the hotspot.

This content type can be used to link to an external URL that will be opened when the hotspot is clicked.


If you need to mark an area or object within a panorama without using text or other media, the title content type is ideal. The hotspot title can be set to always show, hide, or show when the hotspot icon is hovered over.
