You can create and use a Canvas. (and define the Paint method)
Canvas c = new Canvas(){
public void paint(Graphics g){
g.drawImage(img,0,0,this);
frame.add(c);

Are you sure to have the full length file in the library? If you start playing it, will it show the full runtime on the controls?

After updating to 10.6.3, I installed the 10.6.8 update just to start experiencing these font issues. HELP! How do I get the fonts to display correctly in my browsers especially (Chrome & Safari)

What I ended up having to do was open up the Font book & remove duplicates. I knew it was Arial that was causing the problem, so I deleted the duplicate of that font. Inadvertantly I deleted all the Arial regular font, so I had to reinstall one copy. That was the solution. Thanks!

Sports Team Editor: How do I get the players to display in the sports theme?

How do I get the players to display in the sports theme video? I entered the team and players using the sports team editor. Then clicked done and update. But when I play the video only the first players profile shows up. I have the rest of the video done, this is the one remaining mystery. Thank you.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

How can we get the image which is stored in clipboard by labview, is there any functions available like text from clip board

How can we get the image which is stored in clipboard by labview, i can get the text in clipboard by using invoke node directly.but i cannot get the image, is there any functions or vi available.(image is in Png format)

The Read from Clipboard method is, unfortunately, limited to text. If the clipboard contains an image then you need to use OS-specific functions calls. This is an example program for Windows. It's old, but it should still work.

How do I get the images to show up in bridge

How do I get the cr2 thumbnails to go away so that I can view my images?

BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
a screen shot of your settings or of the image could be very helpful too.

How do I get the iMac to display thumbnails and not an icon of jpeg photos?

Hi folks,
I just purchased my first Mac, an Imac. I was browsing through a folder, using Finder, containing photos files from my latest trip.
Under Windows, I used to tell Windows Explorer to show thumbnails of the photos.
How do I get the iMac and Finder to show the thumbnails? It only wants to show a silly jpg icon which doesn't tell me much about what the photo looks like.
Thanks.

That was quick!
I have a folder of JPEG photos on my HD. This folder was created over a year ago when I was using Panther.
When I open it and select "Show View Options" I get a different window with options like "Date Created" and "Date Modified" etc.
There is no preview option or a slider to alter the icon sizes - merely a choice of large or small icons.
Ian.

How do i get an image to display????

this is some code that i have developed to try to get an image to display. i realize that the arrays for images and sources aren't needed but i want to provide room for when i animate things. but i need to get them to display first. what am i doing wrong?
import java.awt.*;
import javax.swing.*;
public class animate extends JFrame implements Runnable {
Thread runner;
int current;
Image img[] = new Image[1];
String[] source = {"thing.gif"};
     public animate() {
          super("animate");
          setSize(210,210);
          setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JPanel pane = new JPanel();
          pane.setBackground(Color.white);
          show();
          Toolkit kit = Toolkit.getDefaultToolkit();
          for(int i = 0; i < img.length; i++) {
               img[i] = kit.getImage(source);
     if(runner == null) {
          runner = new Thread(this);
          runner.start();
     public void run() {
          while(true) {
          current = 1;
     public static void main(String Args[]) {
          new animate();
     public void paintComponent(Graphics comp) {
          Graphics2D com = (Graphics2D)comp;
          if(img[current] != null)
               com.drawImage(img[current],0,0,this);
com.drawString("hello",0,0);

Is that the exact code you're trying to run?
It won't work for several reasons but I'll limit my response to just answering your question. Don't use paintComponent, use paint.
public paint( Graphics g )
