Gerhard Brueckl ( blog | twitter) has already taken this a step further and talks about automating the process by doing everything withing Power BI.Hey guys I am using NGX Dropzone and I notice when I drag an image into the viewer it is in base64, but when I try to read the console.log(event.addedFiles) I have no information being passed to me with the base64 value. You can load URL images, Base64 images and pdf Rotate each image as you wish Download images and PDF files (no additional configuration required). Let me know in the comments if you notice anything else or have any more input on the same. Your best bet would be to add it as a calculated column most of the times.

So make sure you are using small images with this method.Ģ) Since the base64 code can be really long, the code might soon get long & unwieldy if you are using it for multiple images.ģ) Again, due to the length, you might not be able to add it to excel files (excel cells have a limit of 32,767 characters and the base64 code could easily be longer than that). That said, there are some things that I have noticed while working with base64 code:-ġ) Large images usually do not get displayed even if you paste the right base64 code. In the gif below, you can see how the original column (ImgUrl) is not working for George Bush and Donald Trump, but when I replace it with the new calculated column (Img) with the base64 code, it shows the appropriate images. In my case, I am using the chiclet slicer to display the images. This also enables us to mix and match as in my scenario, where some of the entries are coming in as actual URLs and some as base 64 code.Ĥ) Now you can use this column in your report for displaying images. Even if we are embedding the image, the data category has to be set as Image URL. You can substitute the base64 code in the yellow highlighted area.ģ) Make sure that the category of the column is set to Image URL. Note that I am not writing the actual base64 code in the formula above, as it is very long. “Donald Trump”, “data:image/jpeg base64, base64code”
“George Bush”, “data:image/jpeg base64, base64code“, In my case, I want to create a new column that will display the existing URL link if the candidate is not George Bush or Donald Trump, and use this new base64 code for George Bush & Donald Trump. I used this website but you can use any.Ģ) Once you get the Base64 code, prefix it by data:image/jpeg base64, and not you can use it as an expression in any calculated column. Follow the steps below:-ġ) Choose the image that you want and use any Image to Base64 converter to get the Base64 code.

This is where you can use my workaround to embed the images within the report by converting the images into Base64. The Windows Form implementation has two buttons, a down arrow button which is used to convert Base64 Encoded string to Image and show that image in picture box, any errors in string will throw an exception in a message box and another button is up arrow button which is used to convert image in picture box to Base64 string. are not displayed, because the image URLs are no longer valid. The images for the candidates were sourced from Wikipedia and certain candidates like George Bush, Donald Trump, etc. Base 64 encoding is a reliable way to render images and other information in a simple string format without the need for transferring and storing image.

Currently, they are downloading the images and hosting it on their SharePoint Online site.Ģ) Some of the public reports are using images that are hosted in public sites (like Wikipedia), and there is a chance that the image URLs might change (and hence stop displaying the image in the PBI report)ģ) You can access the images offline (for eg, if you are working on Power BI Desktop and there is no internet connectivity).Īnd I completely understood his concerns as I had the same issue with some of the public facing reports that I made, for eg., the US Election report that I had made 1 year back.
During these engagements, I also tend to get a lot of technical questions and one of the questions that came up recently was – How can I embed images for my data categories into Power BI without providing the image URLs?Īs usual, my first question back to the customer was – why do you need this feature or what is the use case here? Some of the reasons he gave were:-ġ) The image will be stored internally in the pbix file, so there would be no need to host the image somewhere else. As part of my new role, I get to spend a lot of time with customers educating them on Power BI and how websites like can make a great difference to budding e-commerce websites.
