Sets the value for the Images property.

<descr>
<p>
<var>SetImages</var> is an overridden method in <var>TTabControl</var> used as
the write access specifier for the Images property. It calls the inherited
method to store AValue in the Images member, and ensures that the value in
Images is then propagated to the Images member in the Tabs property.
</p>
<p>
No actions are performed in the method if AValue is the image list already
assigned to the Images property.
</p>
</descr>
<version>
Modified in LCL version 4.2. The method is declared as an override for the
virtual method in the ancestor class (TCustomTabControl).

<descr>
<p>
<var>Images</var> is a published <var>TCustomImageList</var> property in
<var>TTabControl</var>. It contains the images displayed on the Tabs for the
control.
</p>
<p>
Assigning a new image list to the property causes the widgetset class instance
to be updated; the image list, the tab position, and properties for the page
objects are sent to the widget. The new value in Images is also copied to the
Images member in Tabs (TTabControlStrings). No actions are performed when the
an image list already assigned to the property is assigned to Images again.
</p>
<p>
The Invalidate method is called to cause the control to be redrawn after the
property value is changed.
</p>
<p>
Use ImagesWidth to set the default width and height for the images in the list.
</p>
<p>
Use the indexed Page property to access each TCustomPage object on the tabbed
control to read or write its ImageIndex property. Or, Use OnGetImageIndex to
determine the position in Images for a given page/tab index.
</p>
</descr>
<version>
Modified in LCL version 4.2. Write access is an overridden method where the
image list is copied to the Images in the Tabs property.
