Items can be configured to have an icon – and Sitecore provides an extensive list of them. But you may want to add your own for whatever reason. To do this you’ll need an image suitable for making into an icon, and the ability to resize this image to the correct sizes (Paint.net, Photoshop, GIMP).
For our example we’re making an Arke Icon and we're going to say our largest icon will be 128x128, so we have a transparent png called logo.png to work with:
The image you want to use should have a transparent background unless you want the icon to be a square, and ideally not overly detailed as it will be very small.
Next, we need to make this image into various sizes, and put logo.png into the appropriately named directories, the structure is as follows (if you have several icons, just do the same thing by putting multiple icons into each size folder):
- ArkeIcon
- 16x16
- 24x24
- 32x32
- 48x48
- 128x128
Zip this all up with the same name as the containing folder, so ArkeIcon.zip
Upload this new zip file to /sitecore/shell/Themes/Standard/ and make sure the permissions are correct for your installation (check the other files such as Application.zip for a comparison).
Back within your content editor: each item has an Icon field and you can now enter in your custom icon by entering: ArkeIcon/16x16/logo.png
Once you do this, the new icon will show up in the list of recently used icons as well.
As for adding the new icon set to the list of usable icons – that’s a little more tricky since the list is specified statically (if you know a good way of changing this please share).
You can however modify the existing sets/zips of images, such as the aforementioned application.zip – just add your image to the appropriate directories and you can use it just like all the other icons!
