Hi @elixirgraphics, for strange reason shutter stack in F3 after published, nothings shows on the demo site, then I tried F2 and repeated same process, this time only two images shown out of the 8 default images published… here are the project files dropbox links Dropbox - demo 2.rw8.zip - Simplify your life
Did you use images from Unsplash? If so many likely PNG images. Shutter supports JPGs. Try using your own images from your computer that are JPGs. Unsplash not only uses PNG format for many images, the images are also quite large!
