Wysiwyg in Drupal, CKeditor and elFinder
So I was working to get a better wysiwyg experience in Drupal, as you might know, the out of the box experience of Drupal at this moment is subpar. When you compare it to Wordpress it is quite bare boned.
Drupal 8 will change this though.
But for now you have to add those things yourself, a good combination is CKeditor and elFinder (your file library). If you install these modules (within sites/all/modules/contrib folder), don't forget that both modules need their library as well. For CKeditor it is basically the editor itself that you download from the website (the Drupal module is the wrapper), read the README.txt in the CKeditor folder for instructions, but basically it comes down to:
Download standalone CKEditor from http://ckeditor.com/download. Unzip the
contents of the "ckeditor" directory from the installation package to the
"sites/all/modules/ckeditor/ckeditor" (or "sites/all/libraries/ckeditor") directory.
When you have that working, you can add the elFinder module, when you install this it will give a message that you didn't really install it (very weird), but this is because you need the library. Compare the Module / Library version compatibility list to find the right one. Download, unzip and rename the folder to 'elfinder', instead of 'elfinder-1.2' or whatever the version is.
Copy this to sites/all/libraries and try to install it again, now it should work.
Head over to 'admin/config/content/ckeditor' and edit the profiles (Advanced, Full), you want to check elFinder under the 'File browser settings'.
