PageSpeed score is low

[timotheeg]

The OGP website is our window to the world, and we are an organisation which prides itself in adopting the best web dev practices for government, we should have a high 90+ score at least.

Some low hanging fruit are present, at least for images:

• All png images should be optimized with pngout
• Many png should actually be jpeg files instead .e.g. The image OGP Website Banner is a 3MB png, which could be reduced to less than 500k as a jpg.
• Image resolutions are often much larger than what we display them at, so there is room to reduce image size. That being said, on retina displays, or mobile, the added resolution can look nice, so care should be applied when reducing resolution.
• Many images are displayed with large plain background colors, this can be easily achieved with css and much smaller images
