Step 2: Get the first section and the first paragraph in the section.

Paragraph paragraph = section.Paragraphs[0];

Step 3: Resize images in the paragraph.

foreach (DocumentObject docObj in paragraph.ChildObjects)
{
    if (docObj is DocPicture)
    {
        DocPicture picture = docObj as DocPicture;
        picture.Width = 50f;
        picture.Height = 50f;
    }
}
