The average picture, stored as .jpg, is some 2 MB. So in 2 GB you can store some 1000 pictures. Might be enough if you copy them to your PC once in a while.
I bought a vivitar digital camera. It came with an SD 2GB memory. I'm being told that for normal use I need up to 32GB memory. I bought the camera for it's low price. Now I find out I have to spend more money for a memory card. I maybe at the most take 25 pictures but mostly 5 or six. I'm not a photographer just an average user. Questions: Do I really need 32GB memory or what would I need? Would 8GB fit my needs? Is the memory in terms of how many pictures one can take? 2GB takes x amount of pictures, 4GB x+, 6GB x++ Or how many pictures does each GB take?.
