cameras can also use compact flash which goes up to 8gb last i checked (and its the cheapest format by 25%)

you can get either the mmc or sd from
www.newegg.com pretty cheaply... says your camera has 8mb of storage... shipping is generally 5$
128mb SD -13$
256mb SD - 25$
512mb SD - 42$
1gb SD - 70-80$
prices for mmc are almost identical (and they do go up to 1gb as well), but SD is a more accepted format.
128mb will hold 16x more pics then your internal memory, 256mb 32x etc...
hope that helps.
oh yeah, here's the link to search and buy flash memory (of any type you want):
