Java - Convert image to Base64

The Solution to Java - Convert image to Base64 is

 byte[] byteArray = new byte[102400];
 base64String = Base64.encode(byteArray);

That code will encode 102400 bytes, no matter how much data you actually use in the array.

while ((bytesRead = != -1)

You need to use the value of bytesRead somewhere.

Also, this may not read the whole file into the array in one go (it only reads as much as is in the I/O buffer), so your loop will probably not work, you may end up with half an image in your array.

I'd use Apache Commons IOUtils here:
