Do you have write permission to that folder?

 

[sansalk]

Yes I have permission for the folder, and even i can save pic by using same code for first time but when i was trying to do overwrite(update same) pic
this error comes out..

It sounds like the file is still open. You may have to set the image property of the picturebox control to Nothing for the control to release it. It is also possible that you may have to dispose the image property or even the control.

PicBoxPickers.Image = thumb

thumb.Dispose()

You can't dispose the image that is used by the control. It will normally result in an ArgumentException (Parameter is not valid) at the moment control tries to refresh, but since you here get an ExternalException you are probably using a COM component.

PicBoxPickers.Image = Nothing

This is also not a good idea, dispose the image object before releasing last reference to it, if not you effectively have a memory leak and it could take a long time until finalizer releases unmanaged GDI resources for it.
