First of all, you need to post this in the ATC thread http://forum.purseblog.com/chloe-shopping/authenticate-this-chloe-17672.html
Then you need to somehow get the pics on your desktop and once you post your reply for the thread, you have to click "Go advanced", and then a clipping option should become visible. Then you can upload up to 5 images for one post, if you have more pics you can upload them in several posts. You need to resize the pics though, as the limit is about 195 KB. If you cannot do that you might try www.photobucket.com. You can upload pics from their website from your computer desktop and then post the link in your post! Good luck!
