Try this, and see attached demos. Adapt as needed.
% Draw a small image inset in the upper right corner of a larger plot.
% Ref: https://www.mathworks.com/matlabcentral/answers/60376-how-to-make-an-inset-of-matlab-figure-inside-the-figure#comment_654093
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 18;
x = linspace(0, 1);
y1 = sin(2*pi*x);
figure(1)
% plot on large axes
plot(x, y1, 'LineWidth', 2)
grid on;
ax1 = gca; % Store handle to axes 1.
% Create smaller axes in top right, and plot on it
% Store handle to axes 2 in ax2.
ax2 = axes('Position',[.6 .6 .3 .3])
box on;
fileName = 'peppers.png';
rgbImage = imread(fileName);
imshow(rgbImage);
axis('on', 'image');
% Now draw something back on axis 1
hold(ax1, 'on'); % Don't blow away existing curve.
y2 = cos(2*pi*x/0.7);
plot(ax1, x, y2, 'r-', 'LineWidth', 2);

Why were you unable to? Did you not set up your 'Position' vector properly in the call to axes()???

OK. The form is [x, y, width, height] for the lower left corner of the inset image, so you have to figure out what all those values are. If you want to move the axes, then you must delete the old one before setting the new one.
delete(ax2); % Delete old inset image.
% Make new axes in a new place.
ax2 = axes('Position',[xLeft, yBottom, imageWidth, imageHeight]);
