On the media asset show page, make it so that when you click an image to zoom in, the page scrolls
to the clicked position. For example, if you click on the bottom of an image, scroll down so that
the bottom of the zoomed image is in view.
This makes it easier to view very tall images by letting you click on the part of the image you want
to see.
Redesign the media assets show page to:
* Include sidebar with AI tags and image metadata.
* Include next and previous image buttons.
* Make the image use 100% of the available screen space and to scroll with the window.
* On the upload page, show the video when uploading a video or ugoira.
* On the upload page, show the filesize and resolution beneath the
image, instead of above it.
* On the media asset show page, show the full video or ugoira instead of
just the thumbnail.
