A: This will change depending on the quality setting and how good your camera is at compressing JPEG, but on average a 10MP photo is ~5MP on Fine Setting, so around 1500 pictures on a 4GB card.

A: The following assumptions were made to calculate the number of images per card:
MP = 1,000,000 pixels
1MB = 1,000,000 bytes, 1GB = 1,000MB
TIFF image has 24 bit color depth, one of 16,777,216 colors per pixel
JPEG 100% Quality = Visually lossless JPEG compression with 1:10 ratio of RAW image

Photos – Uncompressed TIFF (24 bits per pixel) Images per card

Example:

Megapixels 4MP
File size (MB) 12.0
512MB 36
1GB 71
2GB 143
4GB 286
8GB 572
16GB 1144
32GB 2288
