Hello,
I am using MATLAB GUI guide to to develop the GUI for my project. I need to select the image from the folder (.png images) and display the selected image on axes in GUI. This action has to be done once the push button is clicked by the user.

Looking forward to hear from you at the earliest .
Thanks Pankaja

If you are using the normal GUI builder, then you create automatically functions for the handles. Put under your buttonfunction the follow commands:
for opening file you can use this function:

for opening a folder you can use:
http://nl.mathworks.com/help/matlab/ref/uigetdir.html
save the this path. I use for this setappdata.
http://nl.mathworks.com/help/matlab/ref/setappdata.html?searchHighlight=setappdata
then you need to recall your figure function and update it.
you can now can get the path by using getappdata

Few work example are given by Doug Hull, you should check these. They explained a lot for me.
