Centre the image in a signature

Can anyone explain how an image can be placed in a signature so that it is in the “centre” as opposed to being attached to the left edge. Previous signature editors in other email clients have included the ability to place an image to left, centre, right, append to baseline etc, but I cant seem to find that ability here.

If this ability doesnt currently exist, can anyone suggest a workaround?

Thanks.

It does have the feature. First you need to actually highlight the image (as if you were highlighting a text area), by click and drag your mouse over the image till the image is overlayed with blue colour (or whatever colour is in your Windows theme). After highlighted, just go to menu “Justify” and choose left, centre, right, etc.
