Android Question [chargeable] MSMySQL question

Regards.
I'm trying to save a picture to mysql
I've seen this code.
db.PeparedStatement ("INSERT INTO adjusted image = images;?")
db.SetPeparedBlob (1 pathtojpg)
db.ExecutePeparedStatement

I have the following question.
I can replace pathtojpg
File.Combine (File.DirRootExternal, "myimage.jpg")
Thank you
