Wondering if anyone knows the recommended image dimensions for the newly announced Twitter Gallery Cards?
Hi Josh, I was wondering the same thing? Did you get an answer on this one from Twitter? I am having major issues with gallery images
@JoanneRoss3. No, I never did figure this out. I just ended up using the same hero image that accompanies each one of my web galleries. See this tweet for an example. https://twitter.com/photogjs/status/442489717271977984
Image sized to 950x546.
Sorry for the delay. Aim for min 200x200, and you should be good.
