A user in your organization tried to export a document from the ImageGallery visual and the download was blocked.<\/strong> This page explains which setting controls this, how to enable it safely (even for a single team only), and exactly what it does. Estimated time: 2 minutes<\/strong>.<\/p>\n ImageGallery is a Power BI visual that displays image galleries and exports them as PDF reports. To deliver the file to the user it relies on Microsoft’s official download API<\/em> ( Microsoft protects that API with a tenant-wide setting that is disabled by default<\/strong> in many organizations. While it is disabled, Power BI shows a “Download unavailable” message and no custom visual can deliver files.<\/p>\n You do not have to enable it for the whole organization. In the same setting, choose “Specific security groups”<\/strong> and apply it to a group (for example Is this visual safe?<\/strong> Why do images show in the report but the export says “Image not exportable”?<\/strong> Do I need to do anything else for licensed users?<\/strong>What is happening<\/h2>\n

Frequently asked questions<\/h2>\n
\nImageGallery does not send report data to external servers for local export: the PDF is generated entirely in the user’s browser. Only if the server hosting the images does not allow direct access (CORS) may the image URLs be relayed through our service on the Cloudflare network (EU data residency, no logging or permanent storage, cache max. 24\u00a0h). Organizations can replace that service with their own proxy from the visual’s settings, or avoid it altogether by enabling CORS on their image storage. Full details in our privacy policy<\/a>.<\/p>\n
\nDisplaying an image requires no special permissions; embedding it in a PDF requires the image server to send the CORS header (Access-Control-Allow-Origin<\/code>). If you use Azure Blob Storage or Amazon S3, it is a configuration option of the service. If the images live in SharePoint or OneDrive behind authentication, export is not possible (a platform limitation that affects every visual on the market) \u2014 we recommend hosting images intended for export in Azure Blob Storage with CORS enabled.<\/p>\n
\nNo. Licenses are managed from the Microsoft 365 admin center, like any Microsoft subscription. This tenant setting is independent of licensing.<\/p>\nQuestions?<\/h2>\n
