Modula Gallery & Gif Images

Hi,
I am trying to have a couple of ‘changing’ images within my gallery. Eg. Image 3, 9 and 5 as gif.
I am using Modula and was trying to set up the ‘changing images’ as GIF files. I do not want all the images to change though, so sliders, etc. are out of the question.
However, the images seem to change to static and do not ‘play’ so to speak.
Any thoughts on how I can get this gallery to work with Gif images or if there are other masonry galleries that work with gif files?
Thank you.
