Having a logo or picture on my own GUI

I have been trying to add a picture or logo to my own built GUI. Despite advices picked up from another thread I have been unsuccessful, mostly due to my lack of understanding how different built in functions such as handles, callbacks, etc work. Here is a brief description: I like to be able to type in a file name that I can use to output my results into. Then there are two buttons to perform different tasks. Now, I have not quite figured out how to inquire for the output file name and definitely I do not know how to have a logo image on this gui. What you see is my understanding of what has been posted on another thread. Thanks for your advice.
function varargout = FastDD(varargin)
% FastDD M-file for FastDD.fig
% FastDD, by itself, creates a new FastDD or raises the existing
% singleton*.
%
% H = FastDD returns the handle to a new FastDD or the handle to
% the existing singleton*.
%
% FastDD('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in FastDD.M with the given input arguments.
%
% FastDD('Property','Value',...) creates a new FastDD or raises the

Put this code in your FastDD_OpeningFcn() function to display an image in an axes on your GUI called axesImage:
% Read in a reza's color logo image.
% Prepare the full file name.
folder = pwd;
baseFileName = 'reza.jpg';
% Get the full filename, with path prepended.
fullFileName = fullfile(folder, baseFileName);
% Check for existence. Warn user if not found.
if ~exist(fullFileName, 'file')
% Didn't find it there. Check the search path for it.
fullFileName = baseFileName; % No path this time.
if ~exist(fullFileName, 'file')
% Still didn't find it. Alert user.
errorMessage = sprintf('Error: %s does not exist.', fullFileName);
uiwait(warndlg(errorMessage));
end
else
% Read it in from disk.
rgbImage = imread(fullFileName);
% Display the original color image.
axes(handles.axesImage);
imshow(rgbImage, []);
title('Reza Logo Image', 'FontSize', 20);
end

Can you show us a screenshot of your GUI in GUIDE and point to the axes where you want your logo to go?
It should be a little axes where you want your logo, retagged to something like axLogo. Then in the opening function, something along the lines of:
I = imread('logo.jpg');
imshow(I,'parent',axLogo);
