I am a techie dunce! I have lots og gif images but although they used to move on my old Motorola RAZR2 V8 & I've saved them as gif files, I have no idea how to open them & make them move! Help!
Open the gif in Gimp, it opens just like any other image file.
If it has several layers, it is animated gif. If it has only one layer it's a still image.
You can preview the animation from Filter/animation/playback.
