For csv to image file, sometimes you can just reshape() and imwrite(), but sometimes you have to do griddata() and imwrite() the result. It depends what the values in the data file represent and whether you have a grid of them or just scattered values.

RGBImage = imread('fingerprint.jpg');
csvwrite(filename, reshape(RGBImage, size(RGBImage,1),[]));
This "unrolls" the M x N x 3 .jpg image into a csv that stores M rows and (N*3) columns.
You might prefer other arrangements for larger images: if you were to be using the data with Excel, you would risk exceeding the maximum number of columns of .xls and .xlsx files.
