Webcam problem

Hello,

Im totally stuck.

I have a webcam on my laptop but my laptop was wiped because of it being too slow ages ago. since then i have not been able to get my webcam working. i was given this laptop and have no software for the webcam. my sister is getting married abroad on sunday and she wants me to see her in her wedding dress on sunday morning but i have no idea how to get the webcam working or where to go.

i would love for someone to give me advice.

many many thanks in advance.

look forward to hearing from you
