[wp-hackers] Newbie Q - can't get get_children to work

[Gaarai]

If you want to attach the same image to numerous posts, using get_child 
for this is the wrong way to go. As you've noted, an attachment can 
have, at most, one parent.

Am I correct in that you simply need to get the attachment details given 
a specific file name?
