If by "leads" you mean USB cords, there are some variations among camera brands and models. I have six digital cameras and other than the DSLR's, all the USB cords are slightly different so are not compatible.
You can avoid all this, by using a card reader. Those of us who have been using digital cameras for a few years stopped connecting our cameras to the computer using a USB cord. Actually card readers can transfer image files faster in most cases.
If you still insist upon using a cord to connect your camera to your computer, take the camera into an electronics store and have them help you find the correct one.
