How does twitter posts feeds to facebook - what data does it use?


Hi - I am new to twitter - I have a twitter account which i connect to my facebook page - what i want to know is when i put my web site URL into twitter www.skyprouk,.com - on my facebook page it shows the correct short link but displays an image which i never uploaded and also the description of my company i never put on twitter and shows my company name to be SkyPro Solutions Limited - which its incorrent
How do i change this ? So its says my company is SkyPro UK Limited? Is twitter taking this info from my web site?
Thanks for any help i can get on this
