Read the image using the read() method of the ImageIO class. Create a ByteArrayOutputStream object. Write the image to the ByteArrayOutputStream object created above using the write() method of the ImageIO class. Finally convert the contents of the ByteArrayOutputStream to a byte array using the toByteArray() method.
There are two ways to convert byte array to String: By using String class constructor. By using UTF-8 encoding.
In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file. Example: Java.
Convert PDF File to Byte Array using C#Load input PDF File. Initialize a Byte Array. Initialize FileStream object. Load the file contents in the byte array.
In Flex 3 or higher, you just need to do:
yourImage.source = yourByteArray;

uhm, well i presume, since it is an image, you have it in a BitmapData, let's say "myBmp" ... then use the following to extract all the data from BitmapData:
var bytes:ByteArray = myBmp.getPixels(myBmp.rect);
and the following to write:
myBmp.setPixels(myBmp.rect, bytes);
note that only the raw 32 bit pixel data is stored in the ByteArray, without compression, nor the dimensions of the original image.
for compression, you should refer to the corelib, as ozke said ...
