This example shows how you can use a GridView to show thumbs of an image
and then display the selected image in a PictureBox.

In fact placing pictures in a cell is simple:

	GridView[r, c].Picture = Picture["path/image.png"]

The only real niggle is that this tends to reset the height of all rows.
So you need a line like after adding the picture:

	GridView.Rows.Height = myRowHeight 

This example gets its images from file - so someone else will have to
answer the database bit. But there is a function in the code which can
be used to create the thumbs.

Note that this example uses Gambas 1.9.47 with Benoit's updated
GridView. You may have to change a few things if you use an older
version of Gambas.

EVENT Transparency? It's not required.

Thanks
