If you're looking to add a picture to your Miro board, there are a few different ways you can go about it.
The first way is to simply drag and drop an image file from your computer onto the Miro board. This will automatically upload the image and add it to your board.
Alternatively, you can click on the Images icon in the toolbar at the top of the screen and select Upload Image. This will open up a window where you can browse your computer for the desired image. Once you've found it, click Open and the image will be added to your board.
Finally, if you want to add an image from the web, click on the Images icon and select Image URL. In the resulting pop-up window, paste in the URL of the desired image and click OK. The image will then be added to your Miro board.
