I have this question :
1-Read an image.
2-Show that image.
3-Write the image to the disk by new name.
4-Show additional info about image.
5-How to get the size of that image.
6-What is the intensity value of the pixel located at position(4,7)?
*I solved the previous five questions, but how can I solve the sixth question
gray = rgb2gray(image)
information = imfinfo('House.jpg')
information = information.FileSize
