Upload from URL or set the URL when inserting the image?
I want to insert into my content some image located on another website. I see two options: to set the URL directly and to do the same using Uploader. What's the difference?
If you want your image to be linked to image on external website, set the URL in the "URL" textbox.
If you want to upload this image by URL to your own server and use it as your own image, use the Uploader dialog. The benefit of this way is you can manage this image using File Manager, edit using Image Editor and you are safe from image is being not accessible or deleted on external website in future.
