Images load delayed when create Controller on Runtime

I have a Tableview which I fill up with rows via code.

var rowController = Alloy.createController('stockRow');
var row = rowController.getView();

The stockRow controller have a simple view with just the TableViewRow with some text and a ImageView

<Alloy>
    <TableViewRow id="row" layout="vertical" inactive="0" itemID="" selected="0">
        <View class="iconColumn">
            <ImageView class="categoryIcon" image="/images/small-icons/small-icon-weather.png" />
        </View>
        <View id="weatherContainer" class="contentHolder" layout="vertical">
            <Label class="itemHeadline">L('weather')</Label>
        </View>
    </TableViewRow>
</Alloy>

But the Image always take about 200 ms (its 200x200px). Currently I solve the problem by placing the image which is in the imageRow in the view which loads the rows and set it to visible = false, then the images appear without delay.

So my question is, can I preload Images such that somehow or how did I deal with those image load delays?
