As you can see from the picture, the BB has a slot for a media or storage card (upper right hand side of the phone in this picture). It's a tiny little thing, but comes in capacities as large as 4 MB. The phone itself can hold a few pictures, but capacity on the phone is limited. I use the card exclusively now, and set the phone so that pictures are automatically stored on the media card.
When I want to move the pictures from the card to my computer, an adapter is required. The tiny microSD card is put in the adapter which is the same size as a standard SD card. The second photo shows the card out of the phone, with the adapter. A standard SD card, the one my point-and-shoot uses, is in the photo for illustration purposes.
After the microSD is securely in the adapter, it can be used as any standard SD card is used. I have printed off pictures at Kinko's using it. The next step for computer down load is to open up your photo managing program and use the down load function. Slip the adapter with the micro into the appropriate slot on your computer and away you go. Now, I'll admit that if you have stored your photos on your phone's memory, I really wouldn't know how to proceed. I would just put them on a memory card and move them from there! My guess is that you would need a cable to connect the phone to your computer. The other option if you have a smart phone like a BlackBerry, iPhone, or Droid is to email the photos to yourself. That just seems complicated to me.
Your computer will offer the option of deleting the photos from the memory card when you are done moving them onto the hard drive. I have never done this. The full memory card is a good back up in case of computer failure. They're little though, so put them someplace safe.
Now, there are phones that use other types of memory cards. Consult your owner's manual, or the manufacturer's website for information. These new highfalutin' phones like the iPhone et al might be different altogether. Never be too proud to read the directions!
And that is a short lesson on managing the photos from your cell phone camera.
