HELP!

Hi there! I'm looking for some help from anyone a bit more knowledgeable than me when it comes to coding a profile on here. Today I tried to add a new blinkie onto my profile, which then almost screwed up my *entire* profile. Here's the thing; the blinkie I used was from a different site than I've used for my other blinkies (https://adriansblinkiecollection.neocities.org/) So the link did look a bit different, I'm curious if that has anything to do with it, like do I need to take away part of the image address to get it to work? 

ex.

"https://adriansblinkiecollection.neocities.org/d20.gif"

(blinkie I have on my profile, works, from the site mentioned above)

vs

(blinkie I want on my profile, from different site)

I found the blinkie I want to use here; https://y2k.neocities.org/blinkies I'm not sure if its an issue with the image address, the site I found it on, or some other miscellaneous reason. If any1 could help I'd really appreciate it :)
