I don't know what are you going to do it!
Saved to the database, it also can not use a program to display!

Write a DLL that have only themselves to find a control or to deal with!

The blob images to a local disk, such as written in "* * *. JPG", and then call "ImageMagick" controls resize, and then put the file into a blob, then save to the database,
