Recursive Image from media picker
Using MS visual studio 2012, c# 4.5 and Umbraco 7.1.

I have been tweaking my master page, and i noticed i had to make images recursive (display on every page).

with property's its no problem, you simply say for example:
```
@Umbraco.Field("pageTitle", recursive: true)
```
this works fine, however for images its a little different as im using a media picker as the datatype for the image, when you do this you need to add some extra code like the following
```
if (Model.Content.HasValue("titleImage"))
{
    var dynamicMedia1 = Umbraco.Media(Model.Content.GetPropertyValue("titleImage"));
    <a class="pull-left">
        <img class="media-object" src="@dynamicMedia1.umbracoFile" alt="" />
    </a>
}
```
this display the image correctly which is great, but as it does not use umbraco.field i cant see how to use "recursive". I've tried looking at some old documentation but doesn't really reference images. And as most will know the new info Isn't quiet available + from what i found there was no mention of recursive images.

Is this possible? Am i missing something?

cheers guys

Hi Steven,

The way you can make a property recursive in Umbraco is by adding a underscore in the front of your ._propertyAlias. Some something like this will make it recursive.

You could try something like this:
```
if(Model.Content.HasValue("_titleImage"))
{
    var dynamicMedia1 =Umbraco.Media(Model.Content.GetPropertyValue("titleImage"));
    <a class="pull-left">
        <img class="media-object" src="@dynamicMedia1.umbracoFile" alt=""/>
    </a>
}
```
Maybe you don't need the if statement since you go recursively up through the content tree, until you find an image.
```
var dynamicMedia1 =Umbraco.Media(Model.Content.GetPropertyValue("_titleImage"));
 <a class="pull-left">
    <img class="media-object" src="@dynamicMedia1.umbracoFile" alt=""/>
  </a>
```
If you are new to razor there a some good resources I think could be nice to know. e.g the cheatsheets

http://our.umbraco.org/projects/developer-tools/umbraco-v6-mvc-razor-cheatsheets

If you´re using Umbraco 7, you can still use the cheatsheets, as far as I know there isen´t the big difference in Umbraco 6 and 7 razor, if any.

Hope this helps,

Hi Dennis

I am sorry. Putting an underscore in front of the alias is not making the result of the Image Picker recursive. Umbraco can't find the image then. "myImage" is ok but "_myImage" is not working.

Am I missing a setting or??

Hi Lars,

What if you do something like this would it work for you?.

@{
    if(Model.Content.HasValue("mainImage", true)){
        var mediaItem = Umbraco.TypedMedia(Model.Content.GetPropertyValue("mainImage")); 
        <img src="@mediaItem.GetPropertyValue("umbracoFile")" alt="@mediaItem.GetPropertyValue("Name")"/>    
    }   
}

Hi Dennis

Thank you for your answer.

Yes it works but with a twist. I need to put "true" in 2 places. One like you suggest and another at the other place where "mainImage" is mentioned. This is the code that works for me. Please notice the places with TRUE.

// Lars
```
@{
    if(Model.Content.HasValue("mainImage", TRUE)){
        var mediaItem =Umbraco.TypedMedia(Model.Content.GetPropertyValue("mainImage". TRUE)); 
        <img src="@mediaItem.GetPropertyValue("umbracoFile")" alt="@mediaItem.GetPropertyValue("Name")"/>    
    }   
}
```

Hi Dennis/Lars,

Thanks for your help recursive image worked for me. But my code is bit different from yours. May be this below code mite help some person.

if (Model.Content.HasValue("Image", true))

{

var mediaItem = Umbraco.TypedMedia(Model.Content.GetPropertyValue("Image", true));

<img src="@mediaItem.GetPropertyValue("umbracoFile")" />

}

Thanks
