Problem with counting images in a desired directory

Hi all,
I am having problem with my code which I need to count the number of images browsing from a path and displaying in a static text box. Here is my codes:
D = uigetdir('*.jpg');
numberfiles = numel(D);

set(handles.result,'String',numberfiles);

The text box shows me "45" while the folder only have 10 jpg images. What is the problem?

How about:

cd(uigetdir);
njpgs = numel(dir('*jpg'))

D will now contain the *name* of the directory

You are asking for the number of elements in the *name* of the directory.

It isn't really clear what you are wanting to do. Possibly use
uigetfile() with MultiSelect turned on, and test the Filename returned
to see if it is char or not; if it is char then it is a single file
name, and if it is not char then it is a cell array of strings and the
length() of that cell array would be the number of selected files.
