A bit more information would have helped us to help you.
Warranty claims have nothing to do with eBay. You shouldn't be using their messaging system to make a warranty claim. EBay messages are for eBay transactions only, and all messages are monitored by eBay. Depending upon how long ago you bought this item, asking for or providing any contact details could cause your account to be automatically suspended.
If you received this item within the last 30 days you should be using eBay's money back guarantee, not negotiating with the seller. EBay would handle it and you would not be required to send photos.
If confused, don't hesitate to ask again with more complete information.
