+Hide files in images!
+
+For each color channel of each pixel in an Image, modify the least significant bit to represent a bit of the Secret file.  
+This changes the RGB value of the pixel by a usually-imperceptible amount.  
+The first 32 bits (10.66 pixels) will be used to store the length of the Secret content in big endian.  
+Then, the Secret's extension is stored. A null byte indicates the end of the extension. This section is of variable length.  
+A file with no extension requires only that null byte. A file with an extension requires 1 additional byte per character.  
+
+Smallest image possible = 16 pixels with 48 bit secret: 32 for header; 8 for null extension; 8 for data.  
+Each Image pixel holds 3 Secret bits, so the Image must have at least `((secretbytes * (8 / 3)) + 14)` pixels.  
+An Image can hold `((3 * (pixels - 14)) / 8)` Secret bytes.
