You can use a custom imReader in the event you have to preprocess the image data in an atypical way.
Otherwise, the standard scipy.ndimage.imread function is used.

@param: glotString is the string passed to the glob function (e.g., '/tmp/image*.png')
@param: DBO file path at which to save the data
@param: resize is a [rows by columns] array to resize the image to, or it is None if no resizing (default is None)
@param: imReader is a function that takes the path to an image and returns a numpy ndarray with the data (r,c,d)
@param: setFloatData will set datum.float_data instead of datum.data (default: False)
@return: the number of images that were inserted into the database
