Caption template – image non centered

I’ve had this issue.

It seems that it should be centered by default, but for some reason it’s broken before.

You need to go into nggallery.css and find this

.ngg-gallery-thumbnail {
    //Some rules
    //Make sure that this next line appears
    text-align: center;
}

If the text-align bit is there and your still not centered, then something else is likely wrong.
