Is there a way to convert a banner image to a base64 using flows / power automate? Any of the get content actions for SharePoint does not work for banner image.

  • Thanks but you are using a file. I am not creating a new file. I want to get the banner image of a news post. Commented Mar 15, 2021 at 14:57
  • That is just a trigger action, just to get the corresponding picture.

  • I'm using get file properties to return the banner image url and this is the url being returned: "https://mysite.sharepoint.com/sites/mysite/_layouts/15/getpreview.ashx?guidSite=42da643b9fb544f0ba63dca47012bb15&guidWeb=31b8be1c434b4f3ea7f697d9cb6b8161&guidFile=0c55849d5de6488ab7cf9163ae00ed51&ext=jpg" which doesn't look right.

  • Could you get the image when you request the url in browser?

  • I figured out that the URL of the banner does not point to the individual site URL (in your case /sites/dev) but instead links to the site-collection itself (mysp.sharepoint.com/_layouts/15). This is a problem for the action "Get File content using path" as it expects a site URL and seems not able to handle the base URL of the site collection. Any tips how to copy the image to a temp SharePoint, get file content and delete the file afterwards?
