overplot contours on image

How can I overplot contours on an image? The image and the contours have different limits. I tried plotting the image using the bottom x-axis and left y-axis and the contrary for the contours. But it doesn't work.
My code:
ax1 = gca;
ax2 = axes('Position',get(ax1,'Position'),...
This only displays the contours. I am unable to see the image.
Can someone provide any assistance?

Regardless of limits, you need to use 'hold on' before executing the contour function or it will always overwrite the image that is in the axis.
If you have tried this then let me know and ill look at it again. That was just what first jumped out at me :)

Great! Haha, I wasn't too sure where to go from there, glad that worked.
Cheers, Angus.
