it's in the bottom part of the code. The image's source property is bound to the imageSource property
Code:
source="{imageSource}"
data binding is more useful when using things like array collections. Here, you just have to make sure that the images source property is being set wherever you want it
Code:
img.source = 'assets/venue1.jpg';
have you tried out that code in my previous post? you should just be able to post the whole thing into your app.
