In a recent project at work, been handling with many hi-fi images in one prototype, so I needed include image pre-loading step or disabling interaction until all images are ready for user to be able to use prototype flawlessly.
I think there're already many existing modules out there, but there might be something new in my module, so sharing it out anyway :)
There're three usecases.
#1. Have array of image urls, load everything and draw prototype.
#2. Have array of image urls, draw prototype first and check progress.
#3. No pre-defined list of images, draw prototype anyway and pull out image links and check progress.
Hope this being useful for some folks in this group.
