How much of the picture frame is visible depends on the width of the frame's border and on the thumbnail mask. All components of a button (frame, thumbnail, frame mask, and thumbnail mask) are scaled so that they meet the same size requirement. For example, say you have a video that's 720x480, and your menu buttons are 120 x 120. For that video's button, DVDA scales it down to 120x80 -- the largest possible size to fit within that frame's outer limit while still maining the correct aspect ratio. But if frame has a solid 10px border, that's 10px all around the edges of your picture that won't be seen. It's there, but it's hidden behind the border because the thumbnail-size matches the frame-size.

Why doesn't DVDA put the image inside the frame's border, you may ask. Well, for starters, DVDA would have to know where that border starts and ends. Reading an image's size is one thing -- figuring out where one color starts and another begins is another (especially for software). Secondly, not all borders necessarily hide the image. Some are a semi-transparent. Some alternate transparency with opaque colors. DVDA can't guess, so it simply matches up the sizes of the overall components. If one particular frame cuts off heads, as it were, I'd suggest using a different thumbnail image (or section of the media, if you're using that for the thumbnail) for the thumbnail or going with a different button frame that doesn't cut off the heads.
