Why this gif url can't be accessed by tiddlywiki?

I have some pictures saved on a gitee repo.

But I have problem when access gif

# gif file can't be shown if saved on gitee

 # jpg is not gif image show normally 

# gif saved on github not gitee show normally 

Why this happened and how to access gif image on gitee?

gitee sends a jpeg as an image

and the gif as text.

So may be it’s a gitee setting somewhere.
