This is a common and classic photographic error - the camera is too far away from the glass so we see lots of background and a tiny little glass in the middle.
If you spend any
time on eBay, then you'll have seen many such examples.
It's actually not a bad record of the glass - there's a nice
black paper insert to provide contrast for the label, there's a
clean neutral background, and there's little in the way of
distracting reflections.
The main problem is that the photographer
is standing too far away from the glass and hence it occupies
only a small portion of the frame.
Sometimes situations
like this are unavoidable - if the camera cannot focus on
objects closer than a few feet, for example. However,
most digital cameras come supplied with software that allows one
to manipulate the image. One of their more important
attributes is that they allow the photographs to be cropped to
exclude irrelevant or distracting backgrounds, which would have
been appropriate here. It doesn't improve the resolution
of the photo but it does present a more pleasing image:
