Usability: There is no easy way to display a thumbnail of a linked image

The autocomplete feature makes it simple to display images from other pages in Confluence, which was previously not easy to do.

However, there is no simple way to insert these images as thumbnails. The autocomplete will add them full-size, and the image browser will only show images attached to the current page.

Therefore, to show a thumbnail version of an image from another page, an RTE user must find it, insert it, then switch to wiki markup and add the correct syntax.

This is not very user-friendly.
