Create thumbnail version of speaker photos #106
Description
Looking at https://csvconf.com, the speaker photos are shown as thumbnails, which is a great design decision. However, the full-sized photo is loaded.
For example:
The current photo Sisi Wei is img/speakers-2020/swei.png is 6.9mb at 2976 px by 2976 px.
The website only needs 200px by 200px. Resizing it produces the following, which is 44kb.
Idea
The team could produce a name_thumb.ext file that is 200px by 200px.
