How to get a picture(memory a picture) froma an axes to another axes of a form?

So I have 2 forms(form1.fig and form2.fig. On first I have a pushbutton1 where I store my photo using uigetfile this is working and a pushbutton2 to make link with the second form form2.fig. On second form I have an axes component where I want to store the image loaded in axes1 from the first form form1.

I'm using guide

The thing I want is to memorize using gca function the photo I select and load in my axes1 on first form on the single axes that I have on form2.fig(form2.fig has only 1 axes component).

Here is the callbacks I did for the two buttons that I have on form1.fig

function pushbutton1_callback
[filename,pathname] = uigetfile({'*.jpg';'*.png';'*.bmp'}); %selection of the file

if ~ischar(filename) %on cancel press OK
errordlg('Error!','Any file selected!'); cancel
return;
end

img = imread(fullfile(pathname,filename)); %reading the image from the path
imshow(img); %displaying on screen
set(handles.text1,'string',fullfile(pathname,filename)); %storing the path of image loaded in a static text component OK

pushbutton1_callback it's functioning

%Now I want to get the current image loaded in axes1 for form1.fig and to set that image loaded in axes1 of form2.fig

function_pushbutton2_callback(hObject, eventdata, handles)

h=gcbo %returns the handle of the graphics object whose callback is executing.
h=get(gca,handles.axes1) % Get handle to current axes so I get the image stored in axes1 component
set(gca,handles.axes1) % put the image I loaded in axes1 of form1.fig in axes1 of form2.fig

I'm stuck using the use of gca and gcbo functiones in pushbutton2_callback.
Pushbutton1_callback it's functionning correctly.

Can you help with an exemple please?

I didn't found any in the documentation so I can understand the main idea.

 

function_pushbutton2_callback(hObject, eventdata, handles)

I try also with this but isn't workingwith set and get) in callback pushbutton2:

a=get(handles.axes1); %get the image I stored in form1.fig on component axes1
set(handles.axes2,a); %set the image on axes2 which is the single component on form2.fig -but it loads me only the photo in axes1 not making the setting for the same picture in the second form(forrm2.fig)
