Answer 1

if it is your server

Open your php.ini (linux: /etc/php.ini , windows: C:\\WINDOWS or C:\\WINNT ) and change or add the following piece of code:

;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Maximum allowed size for uploaded files
upload_max_filesize = 4M

Save your php.ini and restart your server

OR

upload_max_filesize (in php.ini or .htaccess only, won't work using ini_set())
