How many pictures can a one GB hard drive hold?

Answer:
1 GB is relatively small for today's standards, although many 1 GB flash drives exist.

It depends on the size of the photo, which in turn depends on the resolution and the encoding.

GIF and JPEG formats are compressed formats. A good size to "share" with e-mail, web photos, and etc. is less than 100 KB, with resolutions between 500x500 and 1000x1000.

Some newer cameras are able to produce photos in excess of 2MB.

While the large photos are cumbersome for handling, they are better for cropping and editing, and produce better prints.

So....
At 100K, a 1GB drive or flash card could hold about 10,000 photos.
At 2MB, a 1GB drive or flash card could hold about 500 photos.
