My trail cam has a slot for a card now i have a card but once i have pics on it how do i get it on a computer?
Any help would be appreciated?

You either need a multi card reader that plugs into the USB outlet on your computer or depending whether you have a laptop you might have an SD card slot on the side, i know mine does.

Where can u find a reader?

Look for them where you buy your SD cards . They are always near them , or check at a photo store ., Wal-mart has them .
