The following example shows the reload button and sets the left and top coordinates to 50 pixels.
<META HTTP-Equiv="ReloadButton" Content="Visibility:Visible">
<META HTTP-Equiv="ReloadButton" Content="Left:50">
<META HTTP-Equiv="ReloadButton" Content="Top:50">

 <META HTTP-Equiv="ReloadButton" Content="Visibility:Visible"> <META HTTP-Equiv="ReloadButton" Content="Left:50"> <META HTTP-Equiv="ReloadButton" Content="Top:50">

The follwing example shows the Reload button and displays the reaload_up.gif / reload_down.gif images on it (reszing the images if necessary).
<META HTTP-Equiv="ReloadButton" Content="ImageUp:url('http://myaddress/reload_up.gif'); ImageDown:url('http://myaddress/reload_down.gif'); Visibility:Visible">
Copy example to clipboard

 <META HTTP-Equiv="ReloadButton" Content="ImageUp:url('http://myaddress/reload_up.gif'); ImageDown:url('http://myaddress/reload_down.gif'); Visibility:Visible">

Use of Images on Buttons.

Images can be specified as local to the device or on an HTTP / FTP server, just specify the required protocol as part of your URL (file://\, HTTP:// and FTP://). Image will be scaled to the size of the button. JPEG and GIF images are only supported on WM devices. Both CE and WM support BMP files.
Reparsing Meta Tags

Note that PocketBrowser will not reparse a page's meta tags when the page is reloaded. For example if a loaded page contains a 'QuitButton' 'Visibility:Visible' and that page is changed on disk to remove that meta tag; when the page is reloaded the quit button will remain shown. This is for efficiency, to dynamically change tags use InvokeMetaFunction in the Generic object.
Default Positions

By default this control will be placed a the top of the screen. On Windows Mobile if the 'FullScreen' configuration setting is disabled the control will need to be moved, otherwise it will appear beneath the task bar.
Switching to Other Applications

All controls are designed to be shown on top of PocketBrowser. If you require to switch to an application other than PocketBrowser you should minimize PB to ensure the buttons do not remain shown.
Screen Orientation

When the screen orientation changes, either using the ScreenOrientation tag or by rotating a device with hardware support, the command areas will automatically move and resize to fit the new layout. However the buttons themselves are not moved and in some cases this may result in them being off the screen or not in the expected position. If so they must be moved manually by detecting the ScreenOrientationEvent.
