How many 7 megapixel images can a 2GB memory card hold in a digital camera?

It really depends on what quality and resolution settings you choose on the camera, when i went on holiday to Paris 3 weeks ago i took a 7.1 MP Samsung camera with a 2gb SD card in and turned all of the settings to the highest level (for editing purposes) Each photo took up between 2 and 3MB of memory.
If 2gb = 2000MB i am sure you can work out the maths!

Actually 2GB = 2048MB...
