You know you can transfer your images off your phone to your computer right? All you need is a USB cable. Most phones come with one.
Just plug in, connect to USB port on your PC and a window will pop up asking you what you want to do. You want to "view files". Btw this window will only pop up as long as you have your phone's PW unlocked. If you do not have your phone passworded just make sure you have woken/accessed your phone within the last couple of seconds. Anyway, back to viewing files. Now not knowing what kind of phone you have I can't really direct you any further. Your just going to have to look around till you find them. Hopefully they are located in a folder that says "photos" or "pictures". An easier way to find your pictures is to make sure you see your files in a thumbnail view and not a list view.
Even if this all sounds complicated I'd recommend you do this just to explore the insides of your phone anyway. Just don't delete anything. It's OK to delete photo's but only after you have confirmed that you have transfered them to your pc. This is how you free up space on your phone and possibly make it operate faster.
Hopefully you don't have an iPhone. I'm not sure what kind of crappy barriers they have on their phones to isolate them from being compatible with any other piece of electronic device that isn't Apple, but Samsung's don't have this issue, they pretty much connect to anything. Can you tell I don't like Apple?
Anyway, if all this is too much for you just email me the photos

Btw, how long have you had your Duncan? Mine is still fairly young. It has two large heads and two med/small heads. I'm not quiet sure how old it is because it came with my tank and the former owners didn't have it attached to anything and it was free floating around in the tank. (I'm surprised it survived while they had it) Anyway, just trying to figure out the possible growth rate of my Duncan.
