This example uses ToData to convert an image in an ImageWell into a MemoryBlock:

Var mb As MemoryBlock
If productImageWell.Image <> Nil Then
// Get the image data
mb = ProductImageWell.Image.ToData(Picture.Formats.JPEG, Picture.QualityHigh)

// convert the memoryblock back into an image
Imagewell2.Image = Picture.FromData(mb)
