Thumbnails

This website contains links to software which is either no longer maintained or will be supported only until the end of 2019 (CKFinder 2). For the latest documentation about current CKSource projects, including software like CKEditor 4/CKEditor 5, CKFinder 3, Cloud Services, Letters, Accessibility Checker, please visit the new documentation website.

If you look for an information about very old versions of CKEditor, FCKeditor and CKFinder check also the CKEditor forum, which was closed in 2015. If not, please head to StackOverflow for support.

You can set configure thumbnails by using the following settings in the configuration file:

Thumbnails.Url = BaseUrl + "_thumbs/";
Thumbnails.Dir = "";
Thumbnails.Enabled = true;
Thumbnails.MaxWidth = 100;
Thumbnails.MaxHeight = 100;
Thumbnails.Quality = 80;

Url and Dir

The Url and Dir properties defined the folder used to hold all thumbnail images, and the URL to access them. It works just like the BaseUrl and BaseDir settings.

Enabled

By setting Enabled to "false", CKFinder will have no support for thumbnails.

MaxWidth and MaxHeight

Sets the maximum size of the thumbnails displayed in CKFinder. These values are expressed in pixels.

Quality

Sets the quality level used to produce thumbnails in a range from 1 to 100. The smaller the quality the smaller the size of the thumbnail files. Notice that an acceptable value should not be less than 45. For quality thumbnails, 80 is more than sufficient.
