Upload file size limit

I’m using Drupal and I can’t upload files larger than 2MB. Is that a php limit? Where shall I look?

I was told by support that the max upload file size is 7MB. Is there a way to increase this on a shared server?

If it is a php limit, it is possible to upload your own version of php and change the upload file size in the php.ini file. However DH may be able to set a limit in the apache software which I don’t think is user changable.
