Getting a good photo of a glass item can be tricky, especially small items.
Here are a couple of techniques that can help turn your ordinary photos into money shots.
If your camera allows you to adjust your
aperture opening choose a small setting. Somewhere between F/11 and F/22. This will give you maximum depth of field (the amount of area in front of and behind the main subject). Don't forget the tripod, because stopping down the lens is going to mean a slow exposure time, as much as several seconds.
If your camera is an automatic and you can not adjust the
aperture, all is not lost. Remember this is the digital era. With a 5 to 7 mega pixel camera, shooting a picture for a listing - you will have a lot of extra pixels you can loose. In that case, to get the maximum depth of field move your camera back a couple of feet. That should give you more area in focus. Later, in your photo editing software you can crop to your subject.
Because the glass item is very reflective there will be lots of glare spots. These spots can be a distraction to a potential buyer. To eliminate them diffuse the light. A simple way to do that is to use an
eTent. They come in several sizes and are very easy to use. Simply open one up, place the item inside, lights outside and you have diffused light!
The next step is to light the item. Most glass items will display best if photographed from above and slightly behind. This allows the light to travel through the glass and create depth and outline, especially clear glass pieces.
If you are trying for the all white ~ floating on air look, you'll want to light the piece from below as well.
To create the frog photo here is the set-up:

With a simple set-up like the one above you should be able to conquer the most difficult glass subject.
