image file locked after usereplacement module here. For some reason, after an image (say /images/1.jpg) has been used/opened in the application. I cannot later overwrite it (during the application), even after i have closed it. "My.Computer.FileSystem.CopyFile(OpenFileDialog1.FileName, "\images\posters\" & Me.imagenum & ".jpg", True)" The process cannot access the file 'C:...\images\posters\1.jpg' because it is being used by another process. Is there a way to unload this image so that I can overwrite it? As soon as my application quits, the lock is removed. I can tell that my program is locking the file, but the image is not being displayed or used at that time!! Form3.PictureBox1.Image = System.Drawing.Bitmap.FromFile(imgpath) is how it is being loaded. is there a way to unload that? / free up the resource for editing/deletion. another way to do what i'm trying? please help, Thanks, Ted Set the image to Nothing:

I recently ran into a similar problem. I learned that there was a "feature" of GDI+ that keeps the source file locked after the image is loaded. See "http://support.microsoft.com/?id=814675" for details and work-arounds. Cheers, Randy thebh***@gmail.com wrote: Show quoteHide quote > I am creating a website updater program.
