^ Ebay tends to have delay on items that you sell but they should pop up soon...When I list my designer items they can sometimes take half a day to a full day to pop up!

As for your other questions...

You can ship world wide if you like its really up to you to decide...You should be careful when shipping certain items though. Like for designer bags you should never ship to Asia or Itally and France because they have lots of problems with Fraud and Customs. Never ship a item without a tracking number...if the buyer says that they did not receive it at least you would have proof. And always ship to a confirmed address! Also if you sell a high priced item...its always good to have the funds cleared into your account prior to shipping just incase the buyer tries to file a paypal claim against you or do a chargeback after you ship.

With the pictures...if i'm selling my designer bags or something of high value then it's always good to take lots of pictures...I know that this will cost you more but you will get a higher price for it too! When I am listing things that i'm not selling for so much then I would just use one picture which is Free!
