Compress and resize goal images

[brockfanning]

The point of having the goal images in this project is to facilitate usage on websites. But right now they are of a variety of sizes, some very large (1500x1500). They could also be compressed. I propose that we pick a standard size to use, and also run them all through a standard compression process.

What about this as a standard procedure?

• Size: 500x500
• Compress: Run through TinyPNG.com

I get 500 by doubling 250, which is probably the largest any website will actually display these icons at.

I tried this out with the Russian images, for an example, and they went from a combined 1.1MB to 206KB.
