I have traffic cams in an app that show the latest traffic images when opened. Trouble is, if the app's left open, they don't update when clicked on. How can I force the app to get current images when the camera icon is clicked? The page is a "custom html (text)" screen in BT 1.5, which uses local images except for when one of the 4 cam icons is clicked, when it accesses remote images to show the traffic cam image in a modal overlay.

For the screen that contains the traffic cam image, you can configure "Force Refresh" in the Advanced Properties for that screen.

that doesn't do the trick. If I stay on the page, I'm not reloading or refreshing it, I need the links, when clicked to reload up to date images, not just use the ones that were there when that page was originally loaded. Here's the free app, if you want to check out what I mean: http://itunes.apple.com/ca/app/dutyfree/id482152137?mt=8 and it's the top left icon (you may need to refresh the menu if you see a list, not icons...I've got a fix for this going up soon) As a temporary fix, I've added a reload button, but I'd rather have it fetch the up to date image automatically. thanks

That's a darn nice looking app! What sort of screen do you use to display the cam image? If it's an HTML screen, I think you can also set a refresh rate on the page using HTML. I'd have to research that a bit. Mark

I can do a refresh, yeah, I wanted to keep it clean with a force load of the traffic cam images though if possible. Thanks, there are more updates in the works that will make it even prettier!

This might help if you're using an HTML screen: http://en.wikipedia.org/wiki/Meta_refresh

You could google around an try a NSTimer instance that could work.

I got it solved..... adding this to the header fixed it. The problem was that I am using JQuery on the page, and apparently that needs a special 'no cache' script: <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.js"></script> <script type="text/javascript"> $(function(){ $('img').each(function(){ var img=this,src=img.src setInterval(function(){img.src=src+'?'+(new Date())}, 60000 ) }) }) </script>
