Hi! I've noticed a few of SFD organizers tend to link images from outside of our domain. The problem with that is that sometimes URLs change or sites just disappear. I would recommend to upload the images locally and link them as per the wiki syntax {{attachment:image_name.jpg}}. Thank you not to upload 10MiB images but mainly since our hosting is sponsored by Linode we do not really have size constraint. We've also modified the css to have attached images responsive so they'll always scale to the screen width whatever the size of viewers' devices. That was missing from the default theme. You can check http://wiki.softwarefreedomday.org/2016/Colombia/Cartagena for an example. Should you find out other non responsive parts please let us know and we'll try to fix it. Thank you very much. Fred
