url_img =
name_file_img =
>> urlwrite(url_img, name_file_img); Error using urlreadwrite>getFileOutputStream (line 245) Could not open output file "C:\Users\Albm\Documents\MATLAB\2014\10\15\2014\10\15\2014\10\15\2014\10\15\20141015-00:00.jpg".
Error in urlreadwrite (line 69) [file,outputStream] = getFileOutputStream(inputs.filename);
Error in urlwrite (line 38) [f,status] = urlreadwrite(mfilename,catchErrors,url,filename,varargin{:});

You just can't have a colon in a file name, that's all.

Thanks everybody and sorry, but matt dash gave me the perfect answer, some times we forget too basics things. I don't know why. Thank you matt, now I have no problem.

You need to use imwrite() if you want to save an image, not urlwrite().

This code saves the image to my computer just fine for me. Does it work for you?
% Specify the filename (URL).
filename = '';
% Read it in to a variable in my m-file.
rgbImage = imread(filename);
% Display the image.
% Save the image to a file on my local hard drive.
imwrite(rgbImage, 'satellite image.jpg');
