Image Showing Behind Video

I am trying to recreate a page with a different graphic. I am not a programmer and our programmer is not available for several weeks. I have a page and need an image to the right of a video. There was an image there and I changed the name of the image only and now the image is showing behind the video.

Here is the code

<div style="float: left; margin: 0 0 20px 10px;">
<center><img style="border: none;" src="https://uglyopportunities.com/wp-content/uploads/thankyousmall.png" alt="" /></center>
[jwplayer <?php echo $stCodeop; ?> config="opportunities page player large" mediaid="1140" image="https://uglyopportunities.com/wp-content/uploads/opportunities-vis-still.png"]
