Hi,
I have two axes on my gui fig.
when i push a button i want to load two images for each axes. so i tried this.
% --- Executes on button press in Insert.
function pushbutton4_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton4 (see GCBO)
% Invoca duas fotos
% % FOTO 1
[filename,pathname] = uigetfile({'*.jpg';'*.tif';'*.*'}, 'Fotografia Direita');
fich1 = fullfile(pathname,filename);
%
% % FOTO 2
[filename,pathname] = uigetfile({'*.jpg';'*.tif';'*.*'}, 'Fotografia Esquerda');
fich2 = fullfile(pathname,filename);
if(exist(fich1) && exist(fich2))
D=imread(fich1);
E=imread(fich2);
imshow(D,'Parent',axes1);
imshow(E,'Parent',axes2);
end
guidata(hObject, handles);
How can i use this 'Parent' parameter, to make corresponding an image to an specific axes?

Perhaps you should try
imshow(D,'Parent', handles.axes1);
imshow(E,'Parent', handles.axes2);
Anytime you need to refer to any of the controls in your gui, you need to put "handles." before the name of the "tag."

imshow(D, 'Parent', axes1) looks fine already, but as far as I can see in your code, axes1 is not defined. Is it a field of the handles struct?
exist(fich1) is dangerous, because it checks all variables, Java classes, folders and files. Be sure to specify exist(fich1, 'file'). Even then it can be a directory also. To be really sure use:
if exist(fich1, 'file') && ~exist(fich1, 'dir')
I think, exist is not comfortable currently.

The answer of Image Analyst shows, what I meant by "Is it [axes1] a field of the handles struct?".
