% Choose default command line output for test2
handles.output = hObject;
% create an axes that spans the whole gui
ah = axes('unit', 'normalized', 'position', [0 0 1 1]);
% import the background image and show it on the axes
bg = imread('C:\Users\Romesha\Desktop\eye.jpg'); imagesc(bg);
% prevent plotting over the background and turn the axis off
% making sure the background is behind all the other uicontrols uistack(ah, 'bottom');
% Update handles structure
guidata(hObject, handles);
>> test2
Error using set
Invalid handle

Nothing happened to it. bg is the result of imread(), which does not plot. The result of imread() is the data matrix of the image, which is not a handle. What you want to set() against is not bg but rather the result of the imagesc(bg)
