So the task is: 1 Create a website similar to http://www.bodybody.cz. with multiple pages,links and text content. 2 The site should have a photo gallery. It is necessary to make a separate page or section in the admin panel (admin page) to upload photos to the gallery and delete them as [login to view URL] there should be a field to write captions to photos or just leave them empty if the caption isnt necessary.. 3 Contact Form must use api http://www.mailgun.com. The site has sample code and detailed documentation. Everything has to pretty simple and easy. When sending a message through the form the notification has to be send to both sender and reciver. The fields in the contact form have to be agreed with us. 4 Content editing function can be made with mercury editor.

The code in this file is written in bash script. 6) Admin panel (page) is required. Requires integration with dropbox api.
