Just for other people reference This will check to see if it exist and if it comes back false then you can repoint it to a new directory.
for i in range(len(chunk.cameras)):
exist = os.path.isfile(chunk.cameras[i].photo.path)
if exist == False:
#print('copyIm: '+chunk.cameras[i].photo.path)
print(exist)
imPath = delpath + os.path.basename(chunk.cameras[i].photo.path)
#print(os.path.basename(chunk.cameras[i].photo.path))
chunk.cameras[i].photo.path = imPath
print (imPath)
