Thumbnails on publication site

[NoraLoose]

Two issues / questions:

• The first thumbnail on https://m2lines.github.io/publications/ shows a figure from Will Gregory et al., not Aakash Sane et al. Would be good to correct this.
• Some of the thumbnails appear pretty distorted. Is there a way to fix this?
