Rather than dragging the images into a Word document have you tried to use the INSERT ribbon to insert a PICTURE?

To place text below the picture, try using the REFERENCES ribbon to INSERT a CAPTION....OR, right-click on the image and select INSERT CAPTION.

For the image Border, left-click on the image then from the Picture Tools FORMAT ribbon, click on the PICTURE BORDER drop-down option of the Picture Styles section of the ribbon.

Hope this helps...
