Probably you want to use the gnus-article-mime-part-function variable:
see also "(gnus)MIME Commands":

| `gnus-article-mime-part-function'
|      For each MIME part, this function will be called with the MIME
|      handle as the parameter.  The function is meant to be used to allow
|      users to gather information from the article (e. g., add Vcard
|      info to the bbdb database) or to do actions based on parts (e. g.,
|      automatically save all jpegs into some directory).
|      Here's an example function the does the latter:
|           (defun my-save-all-jpeg-parts (handle)
|             (when (equal (car (mm-handle-type handle)) "image/jpeg")
|               (with-temp-buffer
|                 (insert (mm-get-part handle))
|                 (write-region (point-min) (point-max)
|                               (read-file-name "Save jpeg to: ")))))
|           (setq gnus-article-mime-part-function
|                 'my-save-all-jpeg-parts)

Maybe that one helps:
