Skins and many modules have an Images tab. It lets you replace their images, such as the skin's logo or a module's default picture, without touching the files.
The table shows each image with its name and size:
| Column | What it is |
|---|---|
| Default | The image that comes with the skin or module |
| Active | Checked when your custom image is used instead of the default |
| Custom | Your image, with a Delete button |
| Upload Custom | Choose a file to replace the image |
Your image is uploaded and used straight away: Active is checked. To go back to the default, uncheck Active and save. Your image is kept, so you can switch back. Delete removes it.
Additional Images, at the bottom, uploads more images for your own templates. Show one in a template with {jrCore_image image="name.png"}. The same tag shows a replaced skin image, so templates always show the active one.
