كيفية عرض صوره محفوظه فى قاعدة بيانات sqlserver

لدى مشكله فى عرض صوره محفوظة فى قاعدة بيانات

الكود التالى يعمل مع قاعدة بيانات بها جدول مكون من عمودين

1- Picture من نوع Image وطوله 16

2- FileName من نوع Varchar وطوله 250

وعند التنفيذ يعرض فى picturebox

نفس الكود لا يعمل على جدول آخر فيه أربعة أعمدة

1- ID

2- Name نوعه varchar وطوله 30 ويحمل اسم الصورة

3- image نوعه Image وطوله 16

4- filename نوعه varchar وطوله 250

وعند التنفيذ بيطلع خطأ out of memory عند سطر picturbox1.backgroundimage
