Button click to open FileDialog Box and selected any image to display on specific label.

ImageLoader class are used to load images from, and save images to, a file or stream

ImageData class are device-independent descriptions of images

SWT's Image class can be used to display images in a GUI

package rcp_demo.Editor;

import org.eclipse.swt.widgets.FileDialog;
import org.eclipse.swt.custom.CLabel;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.graphics.ImageData;
import org.eclipse.swt.graphics.ImageLoader;


public class ProductEditor extends EditorPart {

        public static final  String ID="rcp_demo.Editor.product";
        private Text text;
        private CLabel lbl_image_text;

        private static final String[] FILTER_NAMES = {
        "Images(*.jpg)","Images(*.jpeg)","Images(*.png)","All Files (*.*)"};

        // These filter extensions are used to filter which files are displayed.
        private static final String[] FILTER_EXTS = { "*.jpg", "*.jpeg", "*.png", "*.*"};

    public void createPartControl(final Composite parent) {

        parent.setLayout(null);
        //Layout with absolute positioning components. 

        text = new Text(parent, SWT.BORDER);
        text.setBounds(25, 57, 169, 19);

        Button btnOpen = new Button(parent, SWT.NONE);
        btnOpen.setText("open");
        btnOpen.addSelectionListener(new SelectionAdapter() {
            @Override
        public void widgetSelected(SelectionEvent e) {

            FileDialog dialog = new FileDialog(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(), SWT.OPEN);
            dialog.setFilterNames(FILTER_NAMES);
            dialog.setFilterExtensions(FILTER_EXTS);
            String result = dialog.open();
            if(result!=null)
               {
                   text.setText(result);
                   Image image=SWTResourceManager.getImage(result);
                   ImageData imgData = image.getImageData();
                   imgData=imgData.scaledTo(200, 200);

                   ImageLoader imageLoader = new ImageLoader();
                   imageLoader.data = new ImageData[] {imgData};
                   imageLoader.save(result, SWT.IMAGE_COPY);

                   System.out.println(imgData.width+"....."+imgData.height);
                   lbl_image_text.setBounds(25,88,imgData.width+10,imgData.height+10);
                   //Image size set to Label
                   //lbl_image_text.setBounds(25,88,image.getBounds().width+10,image.getBounds().height+10);
                   lbl_image_text.setImage(SWTResourceManager.getImage(result));
               }
        }
    });
    btnOpen.setText("open");
    lbl_image_text = new CLabel(parent, SWT.Resize);
    }
}

The CLabel class provides some advanced features over the Label class. This class can display its text label and image label at the same time.

    lbl_image_text.setText("Welcome");
    lbl_image_text.setImage(SWTResourceManager.getImage("Image Path"));
