29933 Directory Modifiction

I'm looking for someone to create modifictaions to Mosets Tree that will allow me to capture thumbshots of web pages. Basically I want a button above the current upload image button saying Get Thumshot. The resulting image will be stored in the /com_mtree/img/listings/ directory and the path written to the database. If possible I would also like a batch process to refresh the whole images directory. Thanks for your attention.
