1. Images for Isotope Album or Page
It is very important that we prepare our images prior to uploading in order to optimize the page loading times. The images may be around 50 kilobytes and no heavier than 100 kilobytes each.
We can add as much images we want to the page, but more than about 25 images and the page may become slow loading.
Images of different sizes will produce an uneven masonry-like effect, we should keep them small, approximately:
- 640 x 480 pixels for landscapes
- 480 x 640 pixels for portraits
There are several image compression software available for the Mac, I use JpegMini with great results: http://www.jpegmini.com
2. Images for Fullscreen Album
Standard sizes for landscape images on a fullscreen album would be:
- 1024 x 768 pixels
- 1280 x 960 pixels
Images may be around 100 kilobytes in order to keep the page as fast loading as possible.
