Adding rasters from folder if it in the data frame extent of the map using ArcPy?

I have 55 rasters located in "G:\desktop\Project\lyr\50k", and i try to add them to MXD file - only if the rasters extent are in the dataframe extent of the MXD file, using python code (in ArcGIS 10.3):

import arcpy

arcpy.env.workspace = r"G:\desktop\Project\lyr\50k"
for rasterFile in arcpy.ListFiles("*.jpg"):
    print rasterFile
    mxd = arcpy.mapping.MapDocument(r"G:\desktop\Project\project.mxd")
    df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
    dfAsFeature = arcpy.Polygon(arcpy.Array([df.extent.lowerLeft, df.extent.lowerRight, df.extent.upperRight, df.extent.upperLeft]),df.spatialReference)
    if arcpy.SelectLayerByLocation_management(rasterFile , "INTERSECT", dfAsFeature):
        addLayer = arcpy.mapping.Layer(rasterFile)
        arcpy.mapping.AddLayer(df, addLayer, "TOP")
        print 'add to map'
    mxd.save()
del mxd, addLayer

but i got en error and i don't understand what is the problem- i placed the rasterFlie and dfAsFeature variable in the arcpy.SelectLayerByLocation_management row, and got mistake:

Traceback (most recent call last):
