Hi Leo,

I will inform the feature request to our developer (under CROS-801), meanwhile actually you can use UseDefaultPicker = false; inside your code (if you are using the MyInventory WebAPI Samples you can put it in code below):

private void ExecuteActivateImagePicker(object parameter)        {
            ImagePickerActivateParameter activateParameter = parameter as ImagePickerActivateParameter;
            if (activateParameter != null)
            {
                activateParameter.UseDefaultPicker = false;
            }
        }

And add action presenter inside it to create custom menu which already can handle each Menu function (Delete photo actually just this.Item.LargeImage = null; & this.Item.ThumbnailImage = null;)
 
Finally just follow how to localizing resource, hope it'll helps :)

Best Regards,
Arief
