When I used a code such as:

<img src="image.gif" style="position: relative; left: 250px; top: 100px;">

I'm able to position it anywhere on the screen. But it's fixed on it's location, even if I resize the window/use a different size monitor.

When I used a code such as:

<center> <img src="image.gif" </center>

I'm not able to position an exact location (it just centers it) but it adjusts it's position relative to the size of the window.

Can I position an image anywhere and have it stay positioned in a spot with the different window sizes using html.

I hope this makes sense. It's difficult to explain/
Thank you.

See the bottom right darker orange box.

I want an image positioned relative to the edges.
