Functions renaming answers from variable, also saving cropped image as file

Hi there, I have a simple question that I couldn't find an answer to.

I wrote a simple function for cropping, where I am cropping multiple images at the same size and dimensions as such:

function [I4] = icrop (Image) 
I4 = imcrop(Image,[2000 1185 776 760]);
imshow(I4)
end

I want to be able to automatically saved the cropped image with a suffix after the variable name. So, if I put in A.jpg, I want the cropped file to be A1.jpg

Any suggestions? Thanks

filename = 'A.jpg';
number   = 1;
[fPath, fName, fExt] = fileparts(filename);
newfilename = fullfile(fPath, sprintf('%s%d%s', fName, number, fExt));

Then use imwrite with the new file name.
