Best way to handle awt.Image buffering in JavaFX

Question

I have a class that takes a String parameter and performs a google search, then it gets the ten images and puts them in an array, that is then handled by another method in the same class. Using Javafx.scene.image would probably allow me to implement the buffering progress easily, but there is a bug with JavaFX Image, that misinterprets the color encoding of normal Images, and saves a weird looking image to the hard drive, so I just decided to use awt.Image.

This is the image search class:

public class GoogleCustomSearch {

    static String key = //custom google id;
    static String cx = // also a custom google id;
    static String searchType = "image";
    static java.awt.Image[] publicImageArray;


    public static java.awt.Image[] Search(String searchParameter,int start) throws IOException, URISyntaxException{

        String formatedText = URLEncoder.encode(searchParameter,"UTF-8");

        URL url = new URL("https://www.googleapis.com/customsearch/v1?" + "key=" +key + "&cx=" +cx + "&q=" +formatedText + "&searchType=" +searchType +"&imgSize=medium" + "&start=" + start + "&num=10");
        System.out.println(url);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/json");
        BufferedReader br = new BufferedReader(new InputStreamReader( ( conn.getInputStream() ) ) );
        GResults results = new Gson().fromJson(br, GResults.class);

        java.awt.Image [] imageArray = new java.awt.Image[10];
        //JProgressBar prb = new JProgressBar();
        //MediaTracker loadTracker = new MediaTracker(prb);
        for(int i = 0; i<10; i++){
            try {
                imageArray[i] = ImageIO.read(new URL(results.getLink(i)));
            }catch (java.io.IOException e){
                imageArray[i] = ImageIO.read(new File("C:\\Users\\FILIP.D\\IdeaProjects\\Manual_Artwork\\src\\MAT - NoImage.jpg"));
            }

        }
        conn.disconnect();

        return imageArray;

    }

    public static BufferedImage getImage(String searchPar, int index, boolean newSearch) throws IOException, URISyntaxException {
        int adaptedIndex;
        int start;
        BufferedImage bimage;
        if(index<10){
            adaptedIndex = index;
            start = 1;
        }else if (index<20){
            start = 11;
            adaptedIndex = index % 10;
            if(index == 10){
                publicImageArray = new java.awt.Image[10];
                publicImageArray = Search(searchPar,start);
            }
        }else if(index < 30){
            start = 21;
            adaptedIndex = index % 10;
            if (index == 20) {
                publicImageArray = new java.awt.Image[10];
                publicImageArray = Search(searchPar,start);
            }
        }else{
            adaptedIndex = index % 10;
            start = 21; //ovo ce posle 30 da ga vrti u loop prvih 10
        }
        if(newSearch){
            publicImageArray = new java.awt.Image[10];
            publicImageArray = Search(searchPar,start);
            return bimage = (BufferedImage) publicImageArray[adaptedIndex];
        }else{
            return bimage = (BufferedImage) publicImageArray[adaptedIndex];
        }
    }

    public static RenderedImage getLiveImage (int index){
        return (RenderedImage) publicImageArray[index % 10];
    }
}

And this is the snippet of the main GUI class that just handles opening the new image in the array

private void nextImageResult() throws IOException, URISyntaxException {
        if(imgNr == -1){
            imgNr++;
            changeImage(SwingFXUtils.toFXImage(GoogleCustomSearch.getImage(oppenedTrack.getArtistName() + "+" + oppenedTrack.getTrackName(),imgNr,true),null));
        }else{
            imgNr++;
            changeImage(SwingFXUtils.toFXImage(GoogleCustomSearch.getImage(oppenedTrack.getArtistName() + "+" + oppenedTrack.getTrackName(),imgNr,false),null));
        }

    }

To summarise, I need a proper way to show a progress bar in the place of the image before it loads, and it needs not to hang the UI, for which I can use Task. I can optimise the loading of the array with MediaTracker, so it can prioritize loading the first few images first.
