Go the respective folder and check the permissions......you need to give permissions to the folder to write the data into the folder.

baseFileName = sprintf('my new image.png'); % Whatever....
fullFileName = fullfile('Documents/MATLAB/Project/Plate', baseFileName);
imwrite(r, fullFileName);
r is your image, right?
if r is the image then,
just include "sprintf" command in your code for writing your file name.
