Joomla Free extensions

Hello,
I need to reduce the startup image (reduced size) before transferring to FB, because then you can not see the full power and is great in the preview.
Or carry a small version of the image - but even that can be too big for the entire previewing on FB.
Thank you for your reply and help.
