I am using the R2011a version! I am typing img_lab in the command line but i am still getting the error:

??? Error while evaluating uicontrol Callback

??? Index exceeds matrix dimensions.

I have tried with tif images and it works. Maybe your error it is due to the matlab version, which version do you use?
Remember that to run the application it is necessary to type "img_lab" into the command line ;)

When i run the gui, and i choose a photo(.tif) i took a message saying: Index exceeds matrix dimensions.

Error in ==> show_rgb at 16

Is there any idea how to get rid of that problem?
Thank you in advance :)

there is no sound and the words are too small to read

You can modify or completly change the GUI directly with matlab, you have to type "guide" and then click on "open existing gui" and look for "img_lab.fig"
