question is still not clear. But you said your image dimension is 300x255 means
width is 300 and height is 255 right ? then in your code for loop

<DIV style="FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: 12pt">you can’t
go more then 300 in your case otherwise it will crash and also j value should be
