Android Image Dialog/Popup

Is it possible to have just an image popup/come-up in an Android application? It's similar to an overriding the normal view of an AlertDialog so that it contains just an image and nothing else.

SOLUTION: I was able to find an answer thanks to @blessenm's help. Masking an activity as a dialog seems to be the ideal way. The following is the code that I have used. This dialog styled activity can be invoked as needed by the application the same way a new activity would be started

ImageDialog.java

public class ImageDialog extends Activity {

    private ImageView mDialog;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_dialog_layout);



        mDialog = (ImageView)findViewById(R.id.your_image);
        mDialog.setClickable(true);


        //finish the activity (dismiss the image dialog) if the user clicks 
        //anywhere on the image
        mDialog.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            finish();
        }
        });

    }
}

your_dialog_layout.xml

<?xml version="1.0" encoding="UTF-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/image_dialog_root" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"
    android:gravity = "center">

    <ImageView
        android:id="@+id/your_image"  
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src = "@drawable/your_image_drawable"/>

</FrameLayout>

It is crucial that you set the following style for the activity to accomplish this:

styles.xml

  <style name="myDialogTheme" parent="@android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:windowContentOverlay">@null</item>
   </style>

The final step is to declare this style for the activity in the manifest as follows:

 <activity android:name=".ImageDialog" android:theme="@style/myDialogTheme" />

If you just want to use a normal dialog something like this should work

Dialog settingsDialog = new Dialog(this);
settingsDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
settingsDialog.setContentView(getLayoutInflater().inflate(R.layout.image_layout
        , null));
settingsDialog.show();

image_layout.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:orientation="vertical">
    <ImageView android:layout_width="wrap_content" 
        android:layout_height="wrap_content" android:src="YOUR IMAGE"/>
    <Button android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:text="OK" android:onClick="dismissListener"/>
</LinearLayout>
