(Alt method) another method which I often utilize is to insert a pic (add image box) from my computer into the image. Then you bypass the whole dot-and-resize process. Here I started with a kitty and inserted an upvote arrow (always a popular choice)! ;-). To get images such as the upvote arrow, search upvote arrow png. Look for a checkerboard background. It may take some trial and error, but you can usually find an image that works.
