Modx Evo Cleaning of pictures to document

Hello Everyone.
Modx evo 1.0.6-d1, you Know what the old version. It's not about the version and the plugin!
Need to write a plugin, most likely that will work 1 time and cleans the documents.
The essence of this. There are plenty of published resources have 4 TV parameter with the addresses of the images (img-1 ... img-4).
Need to taken with the publication of resources to find these photos and delete photos. And in TV-ku to put a picture of the dummy.
Also, if the plugin found the document with the file stub, nothing to do with this document.

From you:
1. To write this plugin or Snippet (how convenient). because you need to run it will be 1 time. To provide a check on any document. (Well, I think it is clear why this testowa check.... so as not to accidentally delete all to hell.)
2. Instructions for implementation.
3. Do on your server. Access does not give.
