[development] Historic Monument Module

[Chris McGinlay]

Hi,

I am currently developing a module aimed at custom display of images 
associated with historic monuments. 

I have a problem with the way I have extended the image.module using 
hook_form_alter()

The module is here:
http://drupal.org/project/monument

Can someone advise me on this question:
Using hook_form_alter in monument_image.module means that in effect every 
image becomes a monument_image. I need to find a way of extending the image 
module without forcing each image to have this extra data.

Thanks

Chris
