# Theme system

The ***Theme system*** of Remote Desktop Manager is still in its infancy and will evolve in future releases. You can override most images used by Remote Desktop Manager simply by providing an image in the ***Theme*** folder, the only requirement is that the file uses a specific name. Most images come in pairs, a small one and a large one. You must override both to be consistent.

### Folder location

The ***Theme*** folder can be found in your local [Configuration folder](https://docs.devolutions.net/rdm/installation/client/configuration-file-location/), under the ***Images*** folder.

### Image file specifications

#### Tray icon

It must be a standard [\*.ico](http://en.wikipedia.org/wiki/ICO_%28file_format%29) file containing at least a 16\*16 image. The name must be Trayicon.ico

#### Small images

Png file, 16\*16 pixels.

#### Large images

Png file, 32x32 pixels.

### Image file names

The file name is standardized as: {EntryType}{Size}.png

For instance, for the ***Folder*** type, the image names are: GroupFolderLarge.png and GroupFolderSmall.png Another example is for RDP sessions, their name is RDPConfigured, resulting in SessionRDPConfiguredLarge.png and SessionRDPConfiguredSmall.png.

Please consult [Image List](https://docs.devolutions.net/rdm/kb/how-to-articles/theme-system/image-list/) to see a list of most images.
