Don't use "image" as the name of your image variable - it's an important built-in function. What is the name of your file you are trying to write? If you comment out the imwrite() line, does the script run fine?

You can get rid of a lot of the warnings by not calling mkdir if the folder exists:
Replace
mkdir(dataFolderName);
by
if ~exists(dataFolderName, 'dir')
mkdir(dataFolderName);
end
then you'll have to put the imwrite back in so I can see what the error for that is. Perhaps you can't write to the folder, like it's on a readonly drive or need admin permission or something.
