MyBB Hacks

I have a idea for using calendars (the best one without using xThreads).

But I need at least one attachment by event. Somebody knows a way to approach this or a plugin that already does it?

Otherwise I try to paste my image with BBCode [img]..

Not quite sure what you mean - there is a plugin for 1.4 called sign up sheet - it lets users sign up to an event on the calendar. It is on the mybb mods site.

No, I meant I want to be able to upload an attachment when writing an event.
