Out of memory loading image on Xamarin.Forms

My app needs to load the same image a certain number of times. Thus, I need to manage the memory usage because after a few iterations it runs out of memory. I am trying to use Garbage Collector, but it isn't working. I am doing this in my Content Page.

My code looks like:

private async Task ExecuteTests(string imageResource) 
{

    // Do stuff

    for (int q = 0; q < NUMBER_OF_TESTS; q++) {

        // Do some work

        await LoadImageAsync (imageResource);

        // Do stuff

        if (q < NUMBER_OF_TESTS - 1) {
            stkImage.Children.Remove(mImageTested);
            mImageTested = null;
            GC.Collect ();
        }
    }
}

private async Task LoadImageAsync(string imageURI) 
{
    mImageTested = new Image { Aspect = Aspect.AspectFit };
    Task<ImageSource> result = Task<ImageSource>.Factory.StartNew(() => ImageSource.FromFile(imageURI));
    mImageTested.Source = await result;
    stkImage.Children.Add(mImageTested);
}

Maybe this can help you manage the memory:
