dunno, you need to ask him
I gave him the code weeks ago.>>12494
tinyboard supports -any- filesize as long as the server configuration allows for it
literally a change in 1 file
I wrote that db-config thing, which'll allow you to change the settings on the fly, but it doesn't support filesizes, though it should be fairly easy to change, as I've made it so it's modular, more or less.
4MB is just a general filesize limit for files in php, it's not really a genius thought, just a regular go-to setting.
