I am manually deleting a particular image present at the beginning of multiples paragraphs in my word file and replacing it with the text "Picture_replaced". Could somebody help me with macro code to perform the above activity automatically.

The image/picture is always present at the beginning of the paragraph.
There are multiple lines which contain the same image to be replaced. Not every line has this particular image.
There are other images/pictures that are present in the file, which should not be touched.
