What is the best way to get the URL to a media picker image in an Umbraco 9 macro? It seems like a pretty easy ask, but Umbraco docs are pretty frustrating to follow (as a designer who dabbles in coding). It seems like a pretty easy ask and I find that with each version of Umbraco they change up the way in which you do something this easy. Here is the code I am using with som eof my unssuccessful tries commented out (some of these worked in previous Umbraco versions)

    @inherits Umbraco.Cms.Web.Common.Macros.PartialViewMacroPage
    @using Umbraco.Extensions


@{
    var testName = Model.MacroParameters["cdsTestimonialName"];
    var testTitle = Model.MacroParameters["cdsTestimonialTitle"];
    var test = Model.MacroParameters["cdsTestimonial"];

    var getTestPic = Model.MacroParameters["cdsTestimonialImg"].ToString();
    @* var fileimg = Umbraco.Media(getBioPic); *@

    @* var fileimg = Umbraco.TypedMedia(getBioPic); *@

    @* var fileImg = Umbraco.Media(getBioPic);
    var fileImgUrl = fileImg.Url; *@



<div class="cds-card-bio">
    <div class="row g-5">
        <div class="col-3">
            <p>@getTestPic</p>
            <img src="/need/the/image-url.jpg" class="img-fluid rounded-circle cds-shadow" alt="@testName - @testTitle">
        </div>
        <div class="col-9">
            <h4 class="cds-m-0">@testName</h4>
            <h5 class="cds-subheader">@testTitle</h5>
            <p>@test</p>
        </div>
    </div>
</div>

}
