Personal website upgrade

I would like to upgrade existing website at [login to view URL] The basic options stay the same. Gallery options changes needed: - drag and drop gallery management - fullscreen mode depending on resolution of user's screen - possibility to reorganize, group and change categories of the gallery in easy and simple way - possibility to reorganize, group and change categories of the blog in easy and simple way And small changes are needed in design. For me it does not matter what tool you are going to use for creating this. The result just should be user-friendly and work quickly. Feel free to ask any additional questions.
