I bought a digital camera and im looking for a 2 gb memory card online, how do i know which one to get?

it takes sd memory cards but are there different sizes for them cause ive seen some different ones?

Sandisk and Lexar come bundled with image recovery software that you copy onto your computer before you format the card. I am sure that the cards all pretty much perform the same, but these brands have a lifetime warranty for some of their products, so that makes me think they are built to higher standards. As far as day-to-day use, I have some generic and some of each brand I named and they all work. The contacts on the brand name cameras seem to have the equivalent of the "thunk" that you look for when you shut a car door to check it's quality, if you know what I mean. You don't wonder, "Is it in there right?" because it just feels right. I don't buy generics any more, though. I just end up getting them "with things" somehow.

Of course, you'll need a decent memory card to get the most out of your A630 and I recommend a genuine Sandisk Ultra II (60X) or Extreme III (133X). Lexar is another excellent card supplier and they have the "Professional" 133X as well as the Platinum 80X to choose from. The 60-80X should be perfectly adequate. Both Lexar and Sandisk come with image recovery software and limited lifetime warranties.

you have to figure out what kind of memory card your camera takes but all of them are not the same size and then resume your search

If you could tell us exactly which model and brand of camera you have, then we could possibly be of more help to you...

Don't mix up sd cards with cards made by the company San Disk. As long as it is SD any 2GB card should work.

any SD will fit your camera. You may want to look for a brand SD card such as Sandisk or Kingston just because ar much reliable than a noname one. Also the write/read speed is an important factor. Look for number above 60x (ideal133x, 150x).
