title: writing image data to text file to creat BMP file
body: <p>I have 1x1 pixel image in BMP. I opened it in notepad. Select ALL and paste the whole data over Serial port monitor, to see what exactly character are in the file..whatever...
    I simply copy the data of BMP file opened in notepad and paste it in another text file, save it as .BMP extension. But no IMAGE is formed. as invalid BMP file.
     when I check the properties of both images (original image and   the image i created by copying the data to new file) by right clicking on it, there is difference in advance information. whats the problem? how can I do that. 
    I have image data in my Controller and want to save it on SD-card as bmp image....</p>
