Adding blinkies not working???

I just got my account actually up and running and I've been trying to add in blinkies I customized from blinkies.cafe, but every single method I've tried they don't show up and are just replaced with the little image error icon. I've tried hosting them w/ discord, imgur, and filegarden but none of them seem to make a difference and I'm starting to think I'm doing something wrong...I've even copied and pasted the code from other blinkies I have that work and replaced the provided links with mine and even THAT doesn't work. I've noticed that most of the blinkies I have that work have spacehey external media links before them and maybe that's the solution? but I don't know how I would get those attached to the link without posting my blinkies on layouts, which it says is currently unavailable. I don't know much about coding but I'm sooooo frustrated cuz this doesn't seem that complicated. Any advice?
