Something wrong with texture

[Anonymous]

Hello,

I am applying texture on 3d object but problem in this (add picture).

What is wrong?

What you're seeing there is just a crude preview of the texture.

What does it look like when you render it?

The warning icon ! in the Materials Editor is an indication that something is wrong.  Could it be that the location of the image file for the bump map is not correct?  In 2018 that is indicated when you expand Bump and see the image file reference.  Check that all the reference files and their paths are correct.  Since image files are cached you can sometimes see an image even after it has been deleted.
