I cannot find any reference to a Nixon W100 camera - however, if you mean a Nikon Coolpix W100 camera, try this link :

You should be able to use any SD card. Try any you have available. If it doesn't show up you may need to format it.

Try these procedures.

replace battery

I have the same camera and had the same problem, reformat memory card or use a new one.

Here some tips to deal with a Nixon Lodown:
1) Sleeping mood (display is off, all buttons lead to the same reaction: display shows time for some secs and then turns off again. This mode is for battery energy saving, switch it on and off by holding (c.a. 2 secs) the light button.
2) ROM FAIL: it happens that the lodown shows ROM FAIL and constantly restarts. It happened on my watch while I tried to change time zones. Here is what to do about it: Bring it to a professional watch repair store and get the battery replaced. The watch restarts automatically and works perfectly fine again. DON'T send it to Nixon, they will charge you for shipping, battery replacement, the new battery etc. Although it should be covered by the guarantee. Just get a new battery, it cost me 16 USD and the watch is good again, waterproof and works perfectly. Nixon authorized repair centers will charge you extra for pressure testing. I had this on my second Lodown, after I had it two weeks only...
3) Watch freezes: All digits are on at the same time, none of the buttons brings a reaction. I had this problem on my first lodown. Just get a new battery, that solves the problem. But again DON'T use authorized Nixon repair centers, it costed me almost 45 USD, just to get a new battery. Although the watch was only 1 year old and guarantee should have covered this case.
In general the Nixon Lodown is a good watch, looks good, has all features you need, as long as it works. The problem with the watch is, the above problems occur pretty often. I have my second Lodown now and I am very disappointed with the Nixon customer service. Although clearly guarantee cases, they will charge you for every single problem you have with the watch. My advice, bring the watch to a regular watchmaker.
After all, I don't understand why the Nixon Lodown manual does not mention all the above issues. The manual is completely useless, very poor from Nixon. You have to dig online to solve any issues on the watch. In summary: The Nixon Lodown watch is good, Nixon customer service and guarantee is a joke. ROM FAIL and freeze is solved with replacing the battery.

Just get a card reader and insert the smart card from the camera into it. It will show up as a drive on you computer. Go into the DCIM file and your pictures will be in there.

I believe that means the range is from 4 seconds exposure to 1/1000 second exposure time, and does not refer to the number of flashes.
Some cameras will flash several times before the main flash while taking a picture if it is set to red-eye reduction (because the first 3 flashes make the subject's pupils go smaller).
Under normal flash photography, there will be only one flash.
If you set the camera to automatic, it will do most ofthe work for you.

hello,

make sure when you press the round selection button on the back of the camera flash option, you press the ok in the center of the button on the back.

it will show brief yellow AUTO in the LCD screen upper right corner for a sec.

when you are going to take a picture holding the shutter button half way down, you should see up at the right corner outside of the LCD screen a red led flashing to indicate flash is ready.

one thing to try if this is not working, find the camera reset option in the menu. after doing this you may have to reset the date & time. it will bring the camera back to default settings

on the bad side if these dont work, possible flash circuit may have failed inside the camera.

good luck!

press the "up" arrow and cycles until the screen which you would like to see by default every photo is taken.
