Gallery grid

[SasanTazayoni]

The current style of the gallery is already very nice, but we could add:

• A small grid gap between the pictures
• A glow hover effect on the pictures
• Pictures to be clickable to open a modal showing the selected picture enlarged
• A border-radius on each picture giving them a "card-like" appearance

The most of it is resolved. Some minor tweak and I will add some animation to the gallery.
