I have a .gif image in my directory. When I open it there is a variable 'cdata' with the pixel data and a variable 'colormap' with the colour map.
I want to display the image, but when I type
image(cdata)
The colours are wrong. I tried setting the colormap using
colormap('colormap')
But this still didn't work.

[I cmap] = imread('image_name.gif','frames','all');
image(I);
colormap(cmap);

When I do this the displayed image is black and white. I can see the correct image in the Matlab preview of the photo, so it must be something to do with the colormap.
