Pictures distorted in lovelace after trying NGINX and local IP

I have some problem with the UI when I am local. If I type in the duckdns SSL in chrome everything looks great, but when I go local http (“not https”)I get the distorted picture in Picture Elements Card. I have /local/picture.png on source path. is there anyone who has any idea? All other types of cards seems to work normally

Solved. I had uppercase *.PNG instread off lowercase *.png in UI lovelace file.
