Thanks!  I also found that copy/pasting PNG images is not consistent.  Uploading is the better way to retain formatting.

Thanks again!

@Alexander Gowan - I found the slide in PowerPoint with the stock image you included and it appears that the woman is not a transparent PNG, but the man is (for me at least). I have attached the PNG files I downloaded from the slide:

And when I move them around in the slide I see that the are not both transparent:

Thanks for the quick response!  The cat image works, but the PNG below (stock from msft) is transparent in PPT but white background in Miro???

@Alexander Gowan - I am not graphics expert, so bear with me. 

The attached PNG is a file I found from a Google search and it does appear as “transparent” in a Miro board:

To learn more about the file you are experiencing issues with, if it isn’t confidential, you could put the PNG into a Miro board and share a link to the board here? If you have a paid plan, you may be able to use Anyone with the link → Can view. You may need to adjust the Board Content Settings to allow for it to be downloaded.
