Question

I’m adding a picture to a word document at a certain bookmark. However, the picture is too big and is forcing text off the page, so I need to be able to change the size of the picture after it is in the word document.

Answer 1

When you insert the image, it should return you an InlineShape, which you can modify:

Word.Application app = new Word.Application();
var doc = app.Documents.Open(@"C:\Users\SomeUserName\Desktop\Doc1.docx");

var shape = doc.Bookmarks["PicHere"].Range.InlineShapes.AddPicture(@"C:\Users\SomePicture\Pictures\1234.JPG", false, true);
shape.Width = 150;
shape.Height = 150;
app.Visible = true;
