filename = uigetfile('*.*', 'MultiSelect', 'on');
image = imread(filename);
axes(handles.axes1);
imshow(image);
guidata(hObject, handles);
set(handles.path,'string',image);

image is not a string, it is an image. Also, if you are selecting multiple images, what should this code do? And what if non-image files are selected?

[filename, filepath] = uigetfile('*.*', 'MultiSelect', 'on');
if isequal(filename, 0)
disp('User aborted file choosing');
return;
end
% Due to "MultipSelect" filename can be a string or cell string.
% Make it a cell string in every case:
filename = cellstr(filename);
for k = 1:numel(filename)
% Append the folder:
file = fullfile(filepath, filename{k});
img = imread(file);
imshow(img, 'Parent', handles.axes1);
set(handles.path,'string', file); % Not "image"
end
"guidata(hObject, handles)" is not useful, if you did not change the handles struct.
Note that the shown code would overwrite the image for each selected file. If 'MultiSelect' should be useful, you have to use different axes to display the images.
