reporting services - SSRS report external image source

Question

I am trying to create a solution to show dynamic images in SSRS reports. I have .NET process that generates Base64 strings that after decoding returned to the client. Here is C# code:

byte[] imageBytes = Convert.FromBase64String(image);
MemoryStream exportStream = new MemoryStream(imageBytes, 0, imageBytes.Length);
exportStream.Position = 0;
return Ok(exportStream);

where image is the Base64 string. It works fine when a client is a Browser. But in the report it shows Red X when I am running it in the report builder. Published report shows nothing at all. Seems like the report doesn't fully understand the return format or something else. Please share any idea.

Thanks
