So I'm trying to change the source of the image depending on an expression to see if its true or not.

HTML

<img ng-src="category.content.Value >= category.content.ValueOneWeekAgo ? 
'Images/green_arrow.png' : 'Images/red_arrow.png'" />

This is how the rendered html looks like:

<img ng-src="category.content.Value >= category.content.ValueOneWeekAgo ? 'Images/green_arrow.png' : 'Images/red_arrow.png'" 
src="category.content.Value &gt;= category.content.ValueOneWeekAgo ? 'Images/green_arrow.png' : 'Images/red_arrow.png'">

I know the variables contains values which was confirmed by debugging. Probably something simple but i can't seem to figure it out.

You can just switch the order in you expresssion to use < instead of >=. You cannot use >= because browser treats it as end of html tag.

<img ng-src="category.content.ValueOneWeekAgo < category.content.Value  ? 'Images/green_arrow.png' : 'Images/red_arrow.png'" >

Other option is to put this code inside a controller and publish as new variable on $scope.

The result is identical to the rendered html I wrote above, part from the order of <=
thats what i ended up doing. ng-src="{{getArrowSrc(category.content.Value, category.content.ValueOneWeekAgo) }}"
You don't need {{}} to call a function. I think you can have other markup errors in you template that are causing error in ng-src attribute.
