Group SP Site (Group image/logo Not Updating)
I am seeing the same behavior and I have been fighting with it for days. This is horrible, I cannot deliver a (OOTB) out of the box solution to the customer, let alone a custom one. Nothing out of the box works the way it is documented and randomly executes its own behavior. This regardless of what size the image or any of its attributes or properties. I am using the modernUI Change the Look => Header => Site logo => Change. Then save of course..
- First it was the translucent background that worked but then randomly changed to black background on its own once the site icon was in place. I eventually changed it to a common background that was the same as the rest of the site to hide it.
- Later for whatever reason about a week from that it changed on its own to https://some_site/sites/some_site_collection/_api/GroupService/GetGroupImage?id=%2759deda41-79a3-443f-bce3-70f8da4f9924%27&hash=636928672156641901
- Changing it in the old Title, description and icon location /_layouts/prjsetng.aspx worked for a moment then it would change back to item in line number two.
- I changed the group icon from inside outlook and it never updated except in outlook. It is still doing the same thing as line item two. This appears to be a REST call for what reason or purpose I have no idea.
SharePoint1968 The logo on a group site is controlled by the group. The old prjsetng.aspx page doesn't know about the group, so it won't update the group logo and any change you make there will soon be overwritten by the group (the same goes for the title and description).
That /_api/GroupService/GetGroupImage call basically goes to Exchange for the group logo, but with a cache in the Site Assets library (the __siteIcon__.jpg and/or .png file). If you delete the cache from Site Assets, it will return a temporary placeholder and kick off an async request to Exchange for the real logo. Normally you can just reload the page after a few seconds and see that it updated. If you're seeing a permanent placeholder, then it's possible that Exchange doesn't have the logo either, or SharePoint can't talk to Exchange to get it.
- Are you using a PNG or jpg?
I noticed that when you use a PNG with an alpha layer it will auto convert it to jpg and change the alpha to black.
Wat h what happens when you go to the teams SharePoint site, site contents, site assets. You will probably see two image files for the site icon. If that's the case, modify your image to not have alpha (I know not ideal right?) Or save as jpg so that it wont convert it. Very strange that it does this. You should be able to upload from teams or sp site info once you have modified your image.
