New File/image dialog

[juarezr@…]

While the current file and image dialog get the work done, it has some deficiencies:

• Too complex for my grandmother use. Too much options.
• It falls behind other windows
• I can click in the editor window while editing

For improving the consider the following sugestions:

• Use a light box for showing the dialogs. It prevents the browser from blocking popups, the user from clicking in the editor and is nice.
  • Example http://jquery.com/demo/thickbox/
  • Example http://stickmanlabs.com/lightwindow/#demos
  • See also http://www.blinklist.com/tag/lightbox/
• Use simple options in the image/file dialog
  • Load from my computer
  • Link in the internet
  • Download from internet
  • File/Image properties
• Just show a few options in the dialog.
  • Alignment
  • Height
  • Width
  • Preview
  • Advanced Options
