Found it. Solution.
In Blueprint Widget, put the anchor in the center of your imported image.
Now in HUD Message Device, choose the position to be custom and in the option under it, you can control the placement of the widget… Center, top center, bottom right… Etc
Another option under that too let you move the image horizontally or vertically but make sure before that to choose the general place first from the previous option I said. (Top, bottom, right…etc)
