Is it possible to create an image gallery in wordpress that is managed by the admin via it's own page / panel. I am not talking about creating a new post and adding custom html for each image. I mean actually having a page in the admin that has the ability to upload and manage your images?
If it is possible how do you go about creating a custom page like this? I understand the PHP side of uploading and manipulating images, but I don't know how to integrate it with wordpress. I don't need a full blow tutorial on how to do this, but if you could just point me in the right direction that would be great.
One issue that comes to mind right away, is if this is possible would upgrading wordpress break the code? Since I assume you have to edit the admin files directly and you can't just do it from your own custom template?
