Add too-large Joomla Components
When trying to add a Joomla! Component that is larger than 2Mb in size, and you are unable to change your MAX_FILE_SIZE setting in either php.ini file or your server PHP Configuration settings, there is still a way to upload these very large components.
First download the component to your computer, un-zip it to a folder using a directory name that makes sense to you, then upload that folder and all its contents to your Joomla! website's tmp directory.
Once complete, go to your Extension Manager and add the folder name to the "Install from Directory" box and click on Install.
This should do the trick and install your new component with minimum fuss.
