Thumbnails are useful for showing people a preview of the report's first page. Thumbnail images are stored in the cloud, so you can link to them with no need to download or upload.\n| **Tip:** See also: [Share reports on social media](/looker/docs/studio/share-reports-on-social-media)\n\nHow thumbnails work\n-------------------\n\nTo display a thumbnail, append the `/thumbnail` endpoint to the URL of your report. This will create a scaled image of the first page of that report. For example, here's the thumbnail URL for the Google Ads report template: \n\n```\nlookerstudio.google.com/reporting/0B5FF6JBKbNJxOWItcWo2SVVVeGc/page/DjD/thumbnail\n```\n\nThe resulting thumbnail image shows the Google Ads report template.\n\nThumbnails are scaled to 320 px x 240 px. For long reports, the thumbnail will try to include the entire report page in those dimensions. For reports with a wide aspect ratio, such 16:9, the thumbnail will try to fit the entire height.\n\n### Update the thumbnail image\n\nTo generate a new thumbnail image, edit and then view the report.\n\n### Who can see the thumbnail?\n\nOnly people with View or Edit access to the report can see its thumbnail. In addition, any data sources for the report must be set to owner's or service account [credentials](/looker/docs/studio/data-credentials). People without proper access see a default Looker Studio logo image instead.\n\nYou'll also see this icon for deleted reports.\n\nUse the thumbnail image\n-----------------------\n\nYou can use thumbnail images in web pages by providing the report's `/thumbnail` URL as the `src` parameter of the HTML `\u003cimg\u003e` tag.\n\nTroubleshooting thumbnails\n--------------------------\n\nHaving trouble displaying a thumbnail image? Check the following:\n\n- Be sure you can view the report. Thumbnails are only available for reports you can see.\n\n- Edit the report, then view it again. This will generate a new thumbnail image.\n\n | **Note:** If you try to access a thumbnail for an older report that hasn't been edited in a while, you may see the default logo image. You can edit the report, and then view that report.\n- All the data sources added to the report must use Owner's Credentials. Thumbnails can't be shown for reports whose data source uses Viewer's Credentials."]]
