Imagelistview only saves small thumbnails of images. Large images are extracted 
every time they  are needed (ie. in gallery mode) To supply large images to the 
control you need to handle the RetrieveVirtualItemImage event.

With imagelistview 5.0 ! In gallery mode, large image will show automatic. But 
in v6.8 large image equal thumnail image.

Thanks.

Hi,

I found and fixed a bug while writing some sample code for you, so please first 
download the latest version (6.9). Afterwards, you will need to handle the 
RetrieveVirtualItemThumbnail event of the control (*not* 
RetrieveVirtualItemImage as I wrote above, sorry for that). In the event, 
you'll need to return a large image for the given item. e.g.:

  object idImage = e.Key;
  Image img = MyGetItemImageFromDatabase(idImage);
  e.ThumbnailImage = img;

Thanks OOzcitak !

i get new problem .. and i need your help.

i have 2 form.

One is: MainForm load image from database to imagelistview, (as thumnail view). 
and using itemclick to open Form 2 with gallery view.

Some time when i close Form 2 i get error message:

"Cross-thread operation not valid: Control 'imgDetail' accessed from a thread 
other than the thread it was created on."  (imgDetail is name of imagelistview 
on Form 2).

        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing); >>> error throw here
        }

Thanks oozcitak a lot . And sorry, my English too bad.
