Solved!
Hereafter the code describing how I did it:

browser = new BrowserField();    
String img_1 = "file:///store/home/user/yellow.png"; // File Sistem

byte[] byt_1    = MyUtilClass.readBytesFromFile(img_1);
char[] base64_1 = MyUtilClass.Base64.encode(byt_1);

// Sample of generating HTML: <html><img src="data:image/bmp;base64,Axcfhhòjbnesohokòbw...."></img></html>
String imgTag_1 = "<html><img src= \"data:image/bmp;base64,"+ String.valueOf(base64_1) + "\" ></img></html>";

byte[] contentBytes;       

contentBytes = imgTag_1.getBytes("UTF-8");

// Inject HTML in browser
browser.displayContent(contentBytes, "text/html; charset=UTF-8", "http://mysite.com");

So, this works fine on Torch, but I have poor performances on Curve. I'll specialize the behaviour depending on device type.

if ( Curve == true ) {
// Use: <img src=file:///store/home/user/yellow.png>
} else  {
// Use: <img src="data:image/bmp;base64,Axcfhhòjbnesohokòbw...."></img>
}

I know that is a workaround, but it works!
