I tried that and it bombed here: picCover.Image = picCover.Image.FromStream(New IO.MemoryStream(arr)) might it be a problem with access?
use Dataset to retrieve and save image I am using following lines .there is no error arr = ds.Tables("CompanyInfo").Rows(0).Item("CompanyLogo") CompanyLogo.Image = CompanyLogo.Image.FromStream(New IO.MemoryStream(arr)) there is also an article with demo project(using access) is available in this group. try to search with keyword "Image"
