Select.PDF <img> Not Appearing in Rendered PDF - pdf-generation

Question

I am using select.pdf to output a PDF file. My process starts by grabbing the text of an HTML file in my visual studio project using this:
string strHTML = string.Join(" ", File.ReadAllLines("Template.html", Encoding.UTF8));
Once I have the strHTML set to the text from the HTML template, I run a few replaces to replace variables I have in the template, like this:
strHTML = strHTML.Replace("PARAM_A", "My Replaced Value");
Once all of that is done, I render the PDF using:
PdfDocument doc = converter.ConvertHtmlString(strHTML);
My problem is this - In the Template.html file I have an HTML img that has a src property set to an image in a Publicly Available Azure BLOB container, like this:
<img style="float:left; height:125px; width:125px" src="FULL PATH TO PNG IN AZURE BLOB CONTAINER" />
While developing and debugging on my local machine, everything works great and the PDF includes the image referenced. The project is an Azure Web Job and when I deploy it, the PDF gets generated as expected but the PDF does not include the image.
I read that the Select.pdf ConvertHtmlString method takes two parameters, my strHTML text and also a baseUrl string property, but I'm not sure what to put here in my situation. I am dynamically generating all of the HTML and then trying to output the PDF.
Any advice would be appreciated.

As your description, I can see that you convert complete HTML document to a string, and then convert it to pdf.
Use the command include two parameters:
PdfDocument doc = converter.ConvertHtmlString(htmlString, baseUrl);
Here is a sample works perfectly.
And this is the decompile code may help you to refer:
public PdfDocument ConvertHtmlString(string htmlString, string baseUrl)
{
int num1;
PdfDocument pdfDocument;
short num2;
switch (0)
{
case 0:
label_2:
pdfDocument = (PdfDocument) null;
num2 = (short) 4;
num1 = (int) (IntPtr) num2;
goto default;
default:
while (true)
{
switch (num1)
{
case 0:
if (!GlobalProperties.RenderWithRestrictedEngine)
{
pdfDocument = PdfDocument.ᜀ(this.ᜁ((string) null, htmlString, baseUrl, baseUrl, false));
num2 = (short) 3;
num1 = (int) (IntPtr) num2;
continue;
}
num2 = (short) 5;
num1 = (int) (IntPtr) num2;
continue;
case 1:
case 3:
goto label_13;
case 2:
num2 = (short) 0;
num1 = (int) (IntPtr) num2;
continue;
case 4:
label_3:
num2 = (short) 1;
if (num2 == (short) 0)
;
if (this.Options.RenderingEngine != RenderingEngine.WebKitRestricted)
{
num2 = (short) 2;
num1 = (int) (IntPtr) num2;
continue;
}
break;
case 5:
num2 = (short) 21784;
int num3 = (int) num2;
num2 = (short) 21784;
int num4 = (int) num2;
switch (num3 == num4 ? 1 : 0)
{
case 0:
case 2:
goto label_3;
default:
num2 = (short) 0;
if (num2 == (short) 0)
break;
break;
}
break;
default:
goto label_2;
}
pdfDocument = PdfDocument.ᜀ(this.ᜀ((string) null, htmlString, baseUrl, baseUrl, false));
num2 = (short) 0;
num2 = (short) 1;
num1 = (int) (IntPtr) num2;
}
label_13:
return pdfDocument;
}
}
