 +Works much the same as the getLastGamedata() function in that it traverses the image list from the current position until it finds the end (determined by the //next// value being NULL).
  
 **Example** **Example**
 +
 +This function is only called within getImageList() within data.c, and is used to build the list of image/artwork/screenshot files as set within a metadata file:
 +
 +<code "C">
 +imagefile = getLastImage(imagefile);
 +imagefile->next = (imagefile_t *) malloc(sizeof(imagefile_t));
 +strcpy(imagefile->next->filename, p);
 +imagefile->next->next = NULL;

 +Behaves the same as //getLastGanedata()// and //getLastImage()// but for the game search directories as defined in the application config file. However, the list of game search directories is only parsed once, at startup, so this function remains unused.
