SharePoint 365 ::: Page :::: Header ::: BackGround image does not stay

Hi, K.I. Woollard,

Welcome to Microsoft Community.

Based on the description, I need to collect the following information to troubleshooting:

1. Please new a page again, change it, does the same issue happen?
2. Try use a different account and have a test , does the same issue appear?
3. Please add and edit a page on other sites, can this issue repro or not?
4. The detailed steps he/she did before this page be published.

Please tell us the result.

Best Regards

So the Steps that are take are.

Step A)    Within a Team site (Classic) Click the "Cog" located top Left, And then Select "Add a page"

Step B)  The page  should now be in front of you it Edit Mode.. 

    Hover your mouse over the title [1] , you should see a menu appear above [2] if you hover your mouse over the top menu option, the tool tip help should say "Add Image"

Step c) press the add image button....

Use the next screen to select an image within SharePoint, The screen image below shows me adding a jpg from the "site Assets" area.

Step D) Click "Save and Close" and then "Publish"

Step E) All looks wonderful until you re-visit the page.

Hi Hans,

Please check if the picture you upload still in Site Assets or not.

And test to upload  the picture which format like jpeg, png, does same issue still happen?

Here is a case named Images from site asset library not displayed in sharepoint similar with yours.

Hi Jerry.

Thanks for replying... and some good questions that made me think  .

But unfortunately I tried png and Jpeg, and both suffer the same issue..  The file is definitely there and I can browse to it..

The file is definitely Checked in,and published.. and it cant be a permission issue as i'm using the same user to view as uploaded..

:-( might haft to give upon this one..

But thanks for trying.

Keith.

Jerry,  Do you mind if I ask .. Can you get the background image to stay, on one of these pages ?

Yes, I have tested. But..can't repro this. It's really weird, all the conditions for doing this are satisfied.
