Last month Twitter added an image preview feature that causes pictures and Vines to automatically appear in users' timelines.
Prior to the update users had to manually expand the media or click through to view the full tweet, but we're now shown a small preview window whether we like it or not..
As with all alterations to the Twitter interface, the update was met with outrage from users who always seem surprised when agile and innovative tech companies seek to evolve their product.
The new image previews can occasionally cause problems, like this morning when my colleague Ben Davis caught a glimpse of a very NSFW picture that someone I follow had tweeted, but in general I find they add some much needed variety to my Twitter timeline.
It also presents an opportunity for brands to become creative with the way in which they use images, or else risk appearing a bit sloppy if their picture previews end up looking slightly obscure.
This effort from Burberry is a good example of how not to preview an image:
Yet some brands have managed to come up with some really creative ways of exploiting the new preview window, which in essence is like a small banner ad.

This is a terrific example of how brands can be creative with the new image feature.
Certainly an eye-catching use of the image box.
Supermarket chain Waitrose was extremely fast to adapt to the new feature and as of the beginning of this month all of its images have been optimised to fit the preview window.
This movie promo from CBS Films demonstrates the impact that can be achieved when the image is the right size to fit the preview window.
In general Sephora doesn't make great use of the image preview box, however this example is worth highlighting. It manages to capture all the important information and effectively acts as a banner ad within its feed.
When expanded the tweet just includes a few extra T&Cs and a larger image of the make up product.
Only one of Cadbury's images fits the preview window, but it looks delicious...

Spotify has been particularly creative with the new image preview, posting several tweets with arrows that entice the reader to find out more.

Another ad that is perfectly sized to show up in your timeline whether you like it or not.
Okay, so this tweet didn't come from a brand marketer, but it is a really creative use of the image preview feature. Obviously it requires very swift fingers to ensure that both tweets appear next to one another in your followers' feeds.
