## Remarks
  
If the [ImageLoadMode](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_AjaxControls_BitmapViewer_ImageLoadMode.htm.md) property is set to [RegularTile](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_AjaxControls_ImageLoadMode.htm.md) the original image is divided into square tiles. The tile size equals to TileSize property value. The control loads square fragments of the original image for corresponding tiles which are visible but not loaded yet.
 
Tile size should depend on the displayed image dimensions and the control client area height and width.
