Per page background image with JSON theme

[benjos23]

In my quest to automate report deployment for multiple companies, I'm looking for a way to quickly change the theme of a report. Indeed, I have a "template" report on which other reports depend, each having a different style, for example with colors and corporate background images. I discovered that you can use JSON files to define themes and apply them to the report with a single click. However, with this JSON file, you cannot apply a background image for each page, but only for all pages. For example, we can modify all the background images with this piece of JSON file:

"visualStyles": {
            "page": {
                "*": {
                    "background": [
                        {
                                "image": {
                                    "name": "my_background",
                                    "scaling": "Fit",
                                    "url": "data:image/jpeg;base64,"
                                }, "transparency": 0
                        }
                    ]
                }
            }
        }

However, it seems impossible to define a specific image for each page. As the original feature was added in 2021, I was hoping it would be possible today. For example, I tried to replace the “*” with the page name, but it doesn't work.
Do you know if there's a solution?

Any advice would be appreciated.

Thank you very much.

Hi @benjos23 

It seems that power bi doesn't support this currently.

Maybe you can try to set the backgroud  image manually:

In the format pane, select canvas background and browse picture from your PC in the image box:

Remember to set the Transparency as 0%.

You can set the background for different pages.

Hi @Anonymous,

I realized that the beggining of my message was not sent, so I modified it.
Indeed, the solution you give is the simplest one, but I would like to avoid it, as it requires many clicks. I would like to find a way to automate the changing of themes, and be able to change background image for each page.
