Yes, the image shows in the picturebox… But after i tried your code it occurs an exception.. i will send it, the first thing is in portuguese but here is the translation: “the object reference was not defined with an instance of an object. in”
Check the image!

Are you reading more than 1 image from the database? If yes, your array definition looks wrong to me, it only allows 1 entry:
Dim imageListEntries As ImageListEntry() = New ImageListEntry(1) {}

Look, the black background is the CustomWallpaper Control wich doesn’t load correctly, and then u can see the picturebox that loads the image sucessfully…

When you use a stream the Position changes. So the second time it’s invalid since it’s a the end of stream. Second if the image is a jpg in .NET it uses interlaced rendering (which is a jpeg thing) so if you create it from a stream it keeps the stream open and when you use the stream again it moves to the end invalidating the image (if you enable logging in web,config you see the exceptions). In that case you either keep leave the stream alone (use it only once) or use this instead new Bitmap(Image.FromStream(stream)). This is a common technique when loading jpegs from a stream, So, basically, the second time you use the stream breaks the first image. If it still fails for you attach a test case with an image file that show how it fails. I just tried the sample that Frank attached and it works without issues with pngs.

So, this one is using basically your code, and the picturebox works, but not the CustomWallpaper.. Check this out, it’s more organizated.
