I'm not sure what browse an image means to you. Maybe it means to select an image file from a folder on your computer (browse for an image), in which case you'd do
[baseFileName, folder] = uigetfile({'*.png';'*.jpg';'*.JPG';'*.bmp';'*.tif'})
fullFileName = fullfile(folder, baseFileName)
or perhaps you want to inspect an image's color values:
imtool(rgbImage); % Can also use a gray image.
If you mean something other than one of those two, then please explain in more detail what "browse an image" means.

Hi, I think Mr. Bharath and me are facing same problem. Here Bharath want to say that in some folder or directory he have some image. He want to access it using matlab coading so that he can do some changes to it. Am i right Mr. Bharath?

But I don't know where your difficulty lies. So what's the problem? Just construct the filename, call imread() to bring it from disk into a variable in your program, and start doing something with it.
rgbImage = imread(fullFileName); % or call it grayImage if it's monochrome.

To get a image from any location, try this:
MY_IMAGE = uigetfile({'*.jpg','*.JPG','*.bmp','*.tif'}) % add any extension you need
MY_IMAGE will be a string with your file name, later, you can read it, load it or do whatever you need to do.
For files in a directory other than the working one:
[MY_IMAGE MY_PATH] = uigetfile({'*.jpg','*.JPG','*.bmp','*.tif'})
my_file = fullfile(MY_PATH.MY_IMAGE) % full directory of your file

When I am trying to read image from my desktop following error appears
Error using imread > get_full_filename(line567)
File 'C:\Users\Pehelinie\Desktop\digital-images-week2_quizzes-lena.gif' does not exist
Error in imread (line 374)
fullname = get_full_filename(filename);

OK, so make sure that file exists. Then the problem will go away.
