Grayscale image displayed in weird colors in GUI

Hi,

when I try to display a grayscale .jpg image in a GUI, the image is shown in weird colors:

This is what the image originally looks like:

I use a template for the GUI and display the image as follows:

imageName = 'table.jpg'; 
im_original= imread(imageName); 
axes(handles.axes1); 
image(im_original); 
axis equal;
axis tight;
axis off;

If I display the image using imshow, it is shown correctly. Since the GUI-Part works for other images, I assume that the problem is that I edited the image beforehand. I used GIMP to transform the originally colored image to the grayscale one.

Do you have any idea how I can get the GUI to display the image normally?

Thanks, Chris

colormap(gray(256))

after you image()

Just use imshow() like you did. Walter gave the method to "fix" image (imagesc has the same "feature" but I didn't think image did). But I never use imagesc() or image(). imshow() is now in base MATLAB (no toolbox required) so just use that - it's better.
