Whenever i try to execute this command: a=imread('itsarose.jpg'); It shows an error: Error using imread>get_full_filename (line 516) File "itsarose.jpg" does not exist.
Error in imread (line 340) fullname = get_full_filename(filename);
i just followed it with an imshow command , nothing much.I use MatlabR2018a. What can i do to rectify this?

shital shinde, at the time you execute the imread(), which directory are you cd() to? What is the name you are passing to imread() ? What is the full path of where the file is actually stored?
Do you happen to be using dir() to find files that are underneath a subfolder? If so then when you are constructing the file name you might be forgetting to include the name of the subfolder.

Your 'itsarose.jpg' image has to be in the MATLAB search path for imread to find it. If it is not, you have to provide the full path to it in the file name.

Do not work with relative paths and it is a bad idea to add folders to the path, because it can confuse Matlab substantially, if the added folders contain M-files. Prefer to use absolute paths instead. In which folder is the image file found?
Folder = 'C:\Temp';
a = imread(fullfile(Folder, 'itsarose.jpg'))

get_full_filename is an internal function of imread()

@Walter: Thanks. I've removed the corresponding part from my answer.

Your image file must me in MATLAB serach path. You should keep your image file in current folder. If you are confused you should give full file name like this
dir = 'C:\Temp\Users'; %give directory of image
image_read = imread(fullfile(dir, 'image_name.jpg'));
