Reduce size of the repo (3GB) by removing huge images and files

[viktorsmari]

UPDATE: @Katearmstrong4 and I discussed that we don't need ALL the images so we should be able to resize this considerably.

1. ALL images have been copied to Flickr https://www.flickr.com/photos/fablabbcn where all our images should live from now on.
2. We should keep profile pics, logos etc in this repo, but move bigger images to Flickr
3. Research and discuss which images we need in the repo.

4. Remove the unwanted images with the git rm img/myimage.jpg which should make the repo smaller in size

   Cloning the repo takes a long time, because the size of it is 3.5 GB

Here is a part list of huge images we might consider reducing the size of.

The list is generated with the command:

| git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' \
| sed -n 's/^blob //p' \
| sort --numeric-sort --key=2 \
| cut -c 1-12,41- \
| numfmt --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest

One way to make images smaller in size is: jpegoptim --size=400k *.jpg

Another is to also make them use less pixels. Many images are 3456x2304, or more and we can convert them to 1080x or more.

convert puerta.jpg -quality 50% -resize 1024x puerta.jpg

Resize multiple images to 1600 find . -iname \*.jpg -exec convert -verbose -quality 80 -resize 1600\> "{}" "{}" \;
