To improve the performance while loading images, please check Store Files in File System at CMS Site Manager -> Files.

 

Checking this option enables images to be stored in the file systems. Thus, anytime an image of the given size is needed, it can be loaded directly from the file system and doesn't have to be resized again from the original picture.

 

To be able to store images in the file system, the modify permissions have to be set for the whole web project (See the Disk permissions problems chapter in Kentico CMS Developer's Guide for more details).

 

All metafiles and attachments are stored in the folder specified at CMS Site Manager -> Settings -> Files -> Files folder. If the Files folder is not set, the following  happens:

- The object metafiles that are not assigned to the specific website are stored in <web project folder>/CMSFiles.

- The object metafiles that are assigned to the specific website are stored in <web project folder>/<site name>/metafiles.

- Attachments (they are always assigned to the specific website) are stored in <web project folder>/<site name>/files.
