Queue-Only (No Thumbnails)

(function() {
 new MultipleUpload('#demo', {
 uploadUrl: '/api/upload',
 multiple: true,
 showThumbnails: false
 });
})();

Why turn previews off

showThumbnails defaults to true. Generating a preview means decoding each image in the browser, which is cheap for a handful of photos and expensive for a folder of two hundred. Turning it off gives you a text queue that renders instantly and uses a fraction of the memory.

When the text queue is the better UI

Document workflows — invoices, contracts, scans — gain nothing from a grid of near-identical page thumbnails, and users identify those files by name rather than by appearance. Bulk uploads are the other case: past a few dozen files the thumbnails stop being scannable and the file name, size and progress are what people actually read.
