Resize and Move Layer....Photoshop style

My application need to load image from database in thumbnails....then drag and drop thumbnail into a transparent image (or picturebox) as a separate layer in canvas...
The layer must be resize and move....
I attach a very primitive sample...
Can someone provide a beter sample code to do this...

Thank you

At least for the database part you can follow few links in my signature - you'll learn how to save/retrieve images to/from database.
That of course if you don't already know it.

Thank you .... my problem is not working with database .....but graphic manipulation....
