If you’re taking JPG images in a high-quality compression, how many will you be able to squeeze onto your memory card? That’s a question often asked.

Here’s rough guide to what you can expect from a variety of memory card capacities:

1 MP (megapixel)
32MB card: 91
64MB: 182
128MB: 356
256MB: 731
512MB: 1420

3 MP
32MB: 26
64MB: 53
128MB: 106
256MB: 213

5 MP
32MB: 12
64MB: 25
128MB: 51
