width: 40vw;
display: block;

You need to change the value on this part
top: 0;
left: 0;
This is the one that controls your popup position. Just put numbers until is in the place you want it.

You can also just use other code for images. Maybe they one you had it's not correctly coded.
Try this code and just replace the url with the one on your correctly coded
—div style="float: ; max-height: 400px; position: fixed; right: -30px; bottom: 10px; z-index: 200;"—img src="URL_HERE" alt="GIF"/——/div—
Don't forget to replace the — with <> as you need it.
