How to make Simple-Texture as a sprite?

[noob22]

There are some pictures below which are my settings and contrast.
And there are some different display between a simple texture and a sprite.
I have no idea.Any suggestions?

It's because texture size is not power of 2 (like 64, 128, 256, ...)
You should include it in atlas if possible.

Thanks for your reply.
Certainly we need use UITexture, when we change UI from external picture resourse.
I have got it.
