Din fråga har @imgName, @imgDescription etc men när du skapar dina parametrar så skriver du @img_name etc

Ändra dessa så det stämmer överrens med de som finns i din fråga.

har gjort det nu... men den vill ända att jag ska deklarera.

Aha, du kör med OleDb ser jag nu. Ersätta alla dina parametrar i frågan till enbart "?" alltså:

VALUES ( ?,?,?,? ..... )

Men låt dina andra parametrar vara kvar som dom är. Se bara till att dom läggs till i samma ordning som du har definerat VALUES i din fråga.

OLE DB .Net providers använder ? istället för parametrar med namn.
