What does this line of code mean and how can I fix the error?
<p>I have an error on this line of code and I couldn't step into it because the error pops right away. Could anyone please tell me what is this line of code trying to do exactly?</p>

<pre><code>var image = ws2.Drawings.AddPicture(
    imagesLocations[i].Name, 
    Image.FromFile(imagesLocations[i].Tests
                                     .FirstOrDefault(t =&gt; t.IsReference)
                                     .ImagePath));
</code></pre>

<p><strong>Error:</strong></p>

<blockquote>
  <p>Exception thrown: 'System.IO.FileNotFoundException' in
  System.Drawing.dll</p>
  
  <p>Additional information: C:\Users\.."full path"..\Initial.png</p>
</blockquote>

<p><strong>Some declarations:</strong>       </p>

<pre><code>ExcelWorksheet ws2 = package.Workbook.Worksheets.Add("Images");

// this is a list of locations, and "location" is a custom class                        
var imagesLocations = SelectedSession.GetTests()
    .Where(t =&gt; t.IsReference)
    .Select(t =&gt; t.Location)
    .OrderBy(t =&gt; t.DateCreated)
    .ThenBy(t =&gt; t.Name)
    .ToList();
</code></pre>

<p><code>Test</code> is a custom object of a written class</p>

<p><code>IsReference</code> is a local <code>Boolean</code> for <code>Test</code> under certain condition</p>

<p><code>ImagePath</code> is a local string for <code>Test</code></p>

<p>So the error is that it is trying to take an image from a path to put it in the excel file. However, the image doesn't exist. I need to understand that line of code so I can prevent it from happening. Any help of how can I do that is very helpful. Please and thanks</p>
