img src not working

guys help :')

i'm trying to add my blinkies to my profile but they always show up as the mountain thing

i'm using <img src> correctly, and i've put the image in the parentheses

i've put the actual image links from the websites where i got them, and i've also tried saving them and adding the file name but neither work.

so whats going on?!?!?
