How to check for and remove a photo from an iPhoto album using AppleScript

Question

I want to write an AppleScript to import a photo into an album. If a photo with the same file-name already exists in the given album, I want to remove the existing one first, then proceed with the import. I tried:

if album "MyAlbum" contains "pic1.jpg" then
    remove "pic1.jpg" from album "MyAlbum"
end if

but that doesn't compile. (I know how to do the actual import part.)

Answer 1

It turns out the answer is really simple:

remove (every photo of album "MyAlbum" whose image filename is "pic1.jpg")
