    I seem not to be able to show an extra text in this Img gallery ....

    I found this code in one of my databases, and I assume it was taken from the net at some stage just can't recall where & when I got it, but AS IS it is exactly right so I wanted to use it!
    I was trying to get some text with it or the title for example into an extra text field yet could not make it work to show the text or title of the selectedIndex etc.
    It looks all very strait forward and easy yet NO luck ??? could somebody look at it and suggest an answer !!! would be very much appreciated! Thanks in advance regards aktell

    Code:
    	applicationComplete="service.send()">
    
    
    	
    	<mx:HTTPService 
    		id="service"
    		url="photos.xml"
    		resultFormat="e4x"/>
    	
    	<mx:TabNavigator 
    		width="220"
    		creationPolicy="all">
    		
    		<mx:Canvas 
    			label="List View" 
    			width="100%" height="100%">
    			
    			<mx:List 
    				id="photosList" 
    				width="100%" height="100%"
    				labelField="@title"
    				dataProvider="{service.lastResult.photo}" 
    				change="photosTileList.selectedIndex = photosList.selectedIndex"/>
    			
    		</mx:Canvas>
    		
    		<mx:Canvas 
    			label="Tile View"

    	<mx:Image
    		id="image" 
    		source="{photosList.selectedItem.@image}"/>

    Over night I came across another item which I would like to include yet again tried & did not get unfortunately a result! I'm looking for the idea of showing at creation that the first Image would be included & visible? regards aktell

    Well, it is only fair enough to admit if once was quiet foolish! I was able to solve the first item mentioned as the answer was actually right there I must have been concentrating on this - photosTileList.selectedIndex = photosList.selectedIndex - so in not seeing what I actually needed. Sorry YET plese I'm still searching about the second item to show an Image at first opening ??? regards aktell
