Transferring the site to the engine

Hello, there.

You need to move the site to a well-known engine.

The main tasks are:

1. retain the functionality of the galleries in the portfolio (opening / moving pictures with mosaics, visibility of pictures when pressed / enlarged)
2. Create/implement descriptions of images (at least tags for good indexing in search engines)
3. make it possible to edit each page of the site (tags, page names, etc.).
