If you mean loading an image on matlab gui, just follow these simple steps. 1. copy and paste the image to the matlab directory, check it on top of your matlab desktop.(C:\MATLAB7\work\New Folder) located on top middle of matlab desktop.
2 run this command; A = imread ('file mame.jpg'); imshow(A)
Good luck!
The image will be displayed. Note, file name has extension of class, say jpg, tif etc.

Make sure you make the axes active and then you can use the 'image' or 'imagesc' command. For example, I have a gui where depending on the the value of the slider, I update an image plot. The relevant code looks like:
usrvar = handles.zdata;
axes(handles.imageplot);
imagesc(handles.xdata, handles.ydata,usrvar);
'imageplot' is the tag of the axes in my gui, zdata is what I generate based on user values and is a 2D matrix,. xdata and ydata are usually just the indices of the matrix and aren't necessary.
See the help on 'image' about color maps and grid lines and other options you may or may not want.

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
I upload my images using copyfile because I have the servers I need mapped to drive letters in Windows. You might be able to upload using a URL if you have permission to write to that location.
Be specific in what you want with your questions, otherwise you'll get no answers.
