How many pictures will fit on a compact flash ultra 11 1.0 GB san disk memory card?

This depends on the quality of the pictures (i.e. their resolution and compression)!

However in general the following guidance if given on the San Disk website:

4 Megapixel camera = 715 JPEG pictures on a 1GB card

5 MP = 572 pictures

6 MP = 476 pictures

7 MP = 408 pictures

8 MP = 357 pictures

10 MP = 286 pictures

12 MP = 238 pictures

14 MP = 204 pictures

16 MP = 178 pictures
