You could try the purepac.com website. They have either descriptions or images for most of their products.
Just guessing, but it may be worth starting at Alprazolam 0.5mg -
There is no image, but described as R (purepac logo) on one side; 029 on reverse side; Peach, round, bisected tablet
You will find an image searching for Alprazolam at http://www.drugs.com/image_search.html
Let me know if this does not match up and I'll search further
