[FIX] website: gallery img inside anchor is too large

Steps:
- Go to "Website" > "Go to Website"
- Click Edit
- Add an image gallery
- Add an image to the gallery
- Click the image
- Click on the Link button in the bottom-right of the side panel
- Add a link and save

Bug:
The image is too large.

Explanation:
The flex layout is not carried over to `img` when it's nested into an `a` tag. Redefining the flex layout on the `a` tag fixes the issue.

This fixes portrait images:
```css
height: 100%;
width: 100%;
```

And adding this also fixes landscape and smaller images:
```css
display: flex;
```
