Thanks to GreenArrowTV who received images from The CW, we have a first look at Grant Gustin as Barry Allen (aka The Flash). Gustin will be appearing in the December 4th episode of Arrow, “The Scientist,” as Barry Allen, a police scientist who offers to help Oliver (Stephen Amell) and team with an investigation.

Also in Flash related news today, Deadline is reporting that CW has changed its plans for The Flash. Originally, Barry Allen, played by Grant Gustin, was supposed to appear in three episodes of Arrow this season — episodes 8, 9 and 20 — with the third episode serving as a backdoor pilot to The Flash series. The 20th episode was to feature The Flash in his costume too, but it seems things have changed.
After viewings of episodes 8 & 9 by CW execs, which were very well received, the decision is to give The Flash a full origin story in pilot episode. Deadline says it is unclear if The Flash will actually make a debut is some form in episode 20 still. I think this is definitely some good news for The Flash, as it would seem The CW is feeling confident in the project and willing to explore it more. (Source: Deadline)
