External images can be on a report server in native mode or any other web site, including a report server in SharePoint integrated mode (SQL Server 2016 or prior). When you include external images in your paginated report, you must verify that the image exists and that the report reader has permissions to access the image. For more information, see Images (Report Builder).
Add an external image
In report design view, on the Insert tab, select Image.
On the design surface, select and then drag a box to the desired size of the image.
On the General tab of the Image Properties dialog, enter a name in the Name text box or accept the default.
(Optional) In the Tooltip text box, type text to display when the user hovers over the image in a report rendered for HTML.
In Select the image source, select External.
For an image on a report server in native mode, enter a relative path to the image in the Use this image box. For example, use
../images/image1.jpg.For an image on any web site (including a report server in SharePoint integrated mode), enter a full URL to the image in the Use this image box. For example, use
https://\<SharePointservername>/\<site>/Documents/images/image1.jpg.For more information, see Specify paths to external items (Report Builder).
(Optional) Select Size, Visibility, Action, or Border to set other properties for the image report item.
Select OK.
