Info required on Employee Photo upload

Hi Friends,

Can any of you explain my questions listed below:

1. Is there any storage limit for storing the photos in Content repository ?

2. If not , If I have a requirement to store lot of photos, does it impact the performance of the system in anyway?

3. How to upload photos for a group of employees?

Kindly share the link or document where I can get all the information about the above said questions.

Thanks in Advance.

Regards,

Nithya.
