I want to create a gallery of images like the Integrity Portfolio demo content. I only need the gallery images as I don’t intend to link to a larger image page. I’m willing to optimize my images before uploading them but can’t find reference to a recommended gallery image size (e.g. 600X600, 814X814, etc).
How big should the images be (and while we’re at it, recommending file size for quality/speed)? Thanks.
