Sorry for the lack of points experts, it's all I had left. Many thanks for looking into this though! I was wondering how I would make a program in VB that generated a thumbnail from an existing picture. (Using it's filename to locate it) Thanks a ton!

that example is good, but I want to be able to export the thumbnails into a jpg, bmp, gif, etc. I don't want them to be in some treeview control.

Option Explicit
Dim Temp As StdPicture,Wid As Single, Hei As Single

Private Sub cmdOpen_Click()
CommonDialog1.ShowOpen

Set Temp = LoadPicture(CommonDialog1.FileName)
Wid = ScaleX(Temp.Width, vbHimetric, picThumbnail.ScaleMode)
Hei = ScaleY(Temp.Height, vbHimetric, picThumbnail.ScaleMode)

picThumbnail.PaintPicture Temp, 0, 0, picThumbnail.ScaleWidth, picThumbnail.ScaleHeight, 0, 0, Wid, Hei

End Sub

Hope this helps
