edit pictures

Hello to all. I have a couple of questions.
1) the texarea "es-photo-caption-field" is in three different places:
- In the pop-up photos
- in the modification of an album
- in modifying a photo
If I insert html code in the field when I edit an album, it is accepted but when I insert it in editing pictures or editing photos in the pop-up, is cleared.
Is possible to make sure that the textarea accept html code in the three situations?

2) when I edit an album photo order is: the oldest before and after the newest.
Is possible to sort photos in this way: the most recent first and the oldest after?
When a user upload some photos, if they have to modify them , certainly they want to work on those loaded recently. It would a way to improve the user experience.

It would also need to be able to sort the photos in a personalized way with drag & drop. Is it possible?

Thanks in advance for the answer.
