User-uploaded images from the wysiwyg editor are not showing properly on mobile devices, since they maintain their original size.
For example on this page: https://apps.magicjudges.org/events/10081/ there are 2 images and especially the 2nd (schedule) is unreadable from mobile devices.
The issue can be fixed by adding this css:
#event_info img {
max-width: 100%;
height: auto;
}
(or possibly a different selector like “#content img” if you prefer)
