How to scale a UV Image Texture? I have a tiling texture that I prepared for use as a bump map.

The problem is that it's too big!

I want the texture to display on the model at about 1/8th of the present size, but I can't figure out how to scale it to be finer. The bump map is supposed to resemble fabric fibers, but at present it just looks like scaly clumps because it's too big.

How can I change the mapping to fix this using Cycles nodes without altering my UV map? If this were a procedural texture I could just change the scale value, but I'm not sure what the equivalent approach would be with an image texture.

Thanks
This can be solved by inserting a Mapping node and setting the Scale values as desired.
