Allowing user upload = virus vulnerability?

[tautouonline]

Hi, I was just wondering if by allowing my users to upload files that it would make my site vulnerable to viruses? And if so, how can I prevent this? Or should I stick to them e-mailing me pictures instead of letting them manually uploading images?

Thanks in advance.

you can restrict file type (image type), so they couldn't send any dangerous file (such as exe or php or ...)
