P.S. Do not duplicate forum topics

ok, can you direct me to the forum that address it

This issue was fixed today. Please see changeset cda03c1c1963

Does it apply to version 2.5 no source code?

Yes. Just update the source code according to the changeset (need some developer skills)

1.I open the website thru ftp  using Visual Studio 2010 express edition.
I was able to find the files referenced in the changes set

src/Presentation/Nop.Web/Administration/Views/Product/_CreateOrUpdate.cshtml
But could not find the one below
src/Libraries/Nop.Services/Media/IPictureService.cs.

What I am missing ?

2.However when I open another different project locally nopcommerce 2.50 source code I was able to find both files referenced in the change set on the solution explorer

Will upgrade it to nopcommerce 2.6 from 2.5 solve the problem?

No. It was implemented after 2.65 release. You should wait for 2.70 or use the latest development version (not officially released) which can be downloaded here

Thanks
1.The link you provide is not working
2.Does it mean that I have to live with this issue(Exception Details: System.ArgumentException: Parameter is not valid.) until the latest development version?
