It depends on your OS and drivers... nVidia cards under Windows can be
set in the display control panel or using WGL:
if OpenGL.WGL.EXT.swap_control.wglInitSwapControlARB(): #
Returns 1 if it's working
OpenGL.WGL.EXT.swap_control.wglSwapIntervalEXT(1) # Swap
only at frame syncs
if OpenGL.WGL.EXT.swap_control.wglGetSwapIntervalEXT() == 1:
success = 1
In linux, nVidia cards can be set with the environment variable
__GL_SYNC_TO_VBLANK

Well, how many images are you trying to load? Image doesn't seem
particularly onerous to me...
