You can manage your project’s media and document files (“assets”) in Craft just like entries and other content types.
Assets are main Control Panel navigation. Clicking on Assets in the main Control Panel navigation will take you to the Assets page, which shows a list of all of your volumes in the left sidebar, and the selected volume’s files in the main content area.
From this page, you can do the following:
You can create a subfolder in one of your volumes by right-clicking on the volume in the left sidebar, and then choosing “New subfolder”.
Once you’ve created a subfolder, you can start dragging files into it.
You can create a nested subfolder within a subfolder by right-clicking on the subfolder in the left sidebar, and then choosing “New subfolder”.
You can rename a subfolder by right-clicking on the subfolder in the left sidebar, and then choosing “Rename folder”.
You can delete a subfolder (and all assets within it) by right-clicking on the subfolder in the left sidebar, and then choosing “Delete folder”.
Craft provides a built-in Image Editor for making changes to your images. You can crop, straighten, rotate, and flip your images, as well as choose a focal point on them.
To launch the Image Editor, double-click on an image and click on the “Edit” button in the top-right of the image preview area in the HUD. Alternatively, you can select an asset on the Assets page and then choose “Edit image” from the task menu (gear icon).
Set focal points on your images so Craft knows which part of the image to prioritize when determining how to crop your images for image transforms. Focal points take precedence over the transform’s Crop Position setting.
To set a focal point, open the Image Editor and click on the Focal Point button. A circular icon will appear in the center of your image. Drag it to wherever you want the image’s focal point to be.
To remove the focal point, click on the Focal Point button again.
Like other changes in the Image Editor, focal points won’t take effect until you’ve saved the image.
