[filename]=uigetfile({'*.jpg'},'File Selector');
image=strcat(filename);
axes(handles.axes1);
imshow(image);
set(handles.filename,'string',filename);
function pushbutton3_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton3 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

I've edited your code to improve the readability. Please use the "{} Code" button.

The question is not clear. "Use that image for another pushbutton"?

strcat(filename) does nothing - I assume you need the filepath in addition? See: help uigetfile.

Requiring users to type in the name of the file they want is not user friendly. Why don't you just load up a listbox of all the files that they might choose. See MAGIC: http://www.mathworks.com/matlabcentral/fileexchange/24224-magic-matlab-generic-imaging-component

Also read the FAQ to see how you can transfer variables between callback functions: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F
