My picture in ZOOM

I was trying to post my picture during a zoom session once and before I could post it, it was already there. I am not sure if this was because it was already copied it to the clipboard or not. Later, I couldn't reproduce it and copy the picture to the clipboard and have it show up automatically. I use just the free standard version of ZOOM usually, but I can use whatever version that can do this. I would prefer figuring it out with the standard free version. I rarely use ZOOM, so I am hoping to not have to buy anything to do this. So my question is, how do I post my picture in the downloaded .EXE version of ZOOM? How do I post my picture in the web version of ZOOM?
