I have written a code for my block diagram as shown below:
\documentclass[10pt]{article}
\usepackage{adjustbox}
\usepackage{tikz}
\usetikzlibrary{plotmarks,matrix,decorations.pathreplacing,arrows.meta,calc,chains,shapes.geometric,backgrounds,fit,arrows,positioning}
\tikzset{
block/.style={
draw,
fill=blue!20,
rectangle,
minimum height=5em,
minimum width=6em
},
every label/.append style = {text= blue, align=center},
blockk/.style={
draw,
fill=blue!20,
rectangle,
minimum height=2.5em,
minimum width=2.5em
},
blockkk/.style={
draw,
fill=blue!20,
rectangle,
minimum height=11.3em,
minimum width=14em
},
sum/.style={
draw,
fill=blue!20,
circle,
minimum size=0.5cm,
},
input/.style={coordinate},
output/.style={coordinate},
pinstyle/.style={pin edge={to-,thin,black}}
}

Now, I want to make some changes as shown by the arrows in this picture:
Arrow 1- to make it look as shown, doing it entirely with coding
Arrow 2- to make it look as shown, doing it entirely with coding
Arrow 3- to make it look as shown using an image. use an arbitrary 120*120 (pixels) image
documentclass, b) end withend{document}, c) still show your situation after compile. Thank you – MS-SPO Jul 29 '23 at 14:38
