Flash provides a great way to make your web page interactive with graphical illustrations etc. On the other hand, visiting flash sites occupy your internet bandwidth more. If you're using a dial-up connection and wish to block Flash intro's in websites, you can disable Flash animations by setting a Kill-bit for this ActiveX control:

{D27CDB6E-AE6D-11CF-96B8-444553540000}
Shockwave Flash Object
C:\WINDOWS\system32\macromed\flash\flash.ocx

NOTE: Backup the Registry before modifying it. See this article for more information on backing up the registry keys.

Open Registry Editor by typing REGEDIT.EXE in the Start, Run dialog.

Navigate to the following location:

[HKLM\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility]

Create a sub-key named {D27CDB6E-AE6D-11CF-96B8-444553540000}

In the right-pane, create a new REG_DWORD value named Compatibility Flags

Set the data for Compatibility Flags to 400 (hexadecimal)

To undo the change, merge the REG file which you've created. Or, simply delete the {D27CDB6E-AE6D-11CF-96B8-444553540000} sub-key under ActiveX Compatibility key.
