It is an image, resized and written on in an editor like lunapic.com.
Pick the image you want.
Take to lunapic.com
Click resize too about 600x600.

Take it to your tumblr and upload as an image post. Click on image after and get the url - they allow hotlinking.
Take to your imvu page and log in, and turn off all your panels except my sandbox - add your url here with the img src= html code.
Click save and reload your page!
If you do not know how to do any of this above, then contact me through imvu or here on tumblr. I will try and do it for you but I will have to log in as yourself on imvu. The price in credits will be 5k each time you want me to work on your page. You are free and should update your passcode to your account all the time.
The coffin image on my account I also made on bing copilot for free. That's how I make my images for your use so it is AI. If AI bothers you we shouldn't speak.
