I am not sure how many of you have experimented with the new custom header image functionality of wordpress 3.0 but its actually very cool (enabled by adding the function to your functions.php file).
One of the key things which I find to be extremely useful is that it allows you to upload an image and on step 2 it actually places the image on the admin page and shows you a crop box based upon the header image width/height which was defined in your functions.php file. You now have the ability to move the box around or proportionally increase/decrease the size of the area you want to use.
The problem that I am having here is that I would like to utilize this functionality with my own custom post type. More specifically, I am just looking for the ability to include the upload functionality, defining the width/height and the select/cropping functionality once the image was uploaded. My thoughts are that if someone can show this can be done then I can create all the other functionality I am looking for by adding this to a custom post type and associating custom metaboxes.
Can anyone provide a solution here?
