# For 512 x 512 images foo1 to foo100
reader = vtk.vtkBMPReader()
reader.SetDataExtent(0, 511, 0, 511, 1, 100)
reader.SetFilePrefix('/path/to/foo')   
# %s is the prefix above. %d is the format string for the numbers; 
# Eg, use%03d for files like foo001.bmp, etc
reader.SetFilePattern('%s/%d.bmp')  
reader.SetDataSpacing(sx, sy, sz) # convert to data coords if you want

imageData = reader.GetOutput()

You can pass the image data to whatever image handler you want, eg
vtkImagePlaneWidget...
