Here's how you would do it if the Image was a resource file of the application:

byte[] imgData = null;
InputStream in = Application.getApplication().
        getClass().getResourceAsStream(imgName);
if(in == null) {
    // Handle appropriately
}

try {
    int length = in.available();
    imgData = new byte[length];
    in.read(bytes, 0, length);
} finally {
    in.close();
}

if(imgData == null) {
    // Handle appropriately
}

EncodedImage encodedImage = 
        EncodedImage.createEncodedImage(imgData, 0, imgData.length);

You could also pass a String as a parameter to define the MIME type. These are the supported MIME types:

• "image/gif"
• "image/png"
• "image/vnd.wap.wbmp"
• "image/jpeg" (supported only on Colour devices)
• "image/jpg" (supported only on Colour devices)
• "image/pjpeg" (supported only on Colour devices)
• "image/bmp"
• "image/tiff"

Finally, here's the documentation for 4.5: [EncodedImage Javadocs 4.5][1]
