Just now I realized that CKEditor uploads files into the database (table qa_blobs).
As far as I could see those images are not cached and thus result in slower server handling.
This is why I would like to ask how to change that behavior to have the files saved to a folder on the server, e.g. \uploads\images\
From my understanding, I have somehow to change the "qa-wysiwyg-upload.php" from line 102??
Searching the net regarding CKEditor (which is definitely pain) I found a little discussion about image uploads and absolute paths, if that helps: Image uploading in FCKeditor as well as kind of tutorial here.
I get a bit confused reading about folder vs. database in stackoverflow. Post by John Gietzen:
"FileStream solves most of the problems around storing the files in the DB:
The Blobs are actually stored as files in a folder.
The Blobs can be accessed using either a database connection or over the filesystem."
What is Question2Answer using? What is the best way to serve cached images?
