Let's improve the accessibility of the website

[tryzniak]

Hello. I ran Google Chrome's audit on accessibility and it turns out there are a number of issues. A lot of them it looks to me can be easily fixed like missing alt attributes, buttons without a name, low contrast.
I can work on a PR btw :)
