This component is a dropzone to upload multiple images. It is configured with a max file size of 1 MB and a max number of files of 6.
Here, the EdgeStoreProvider is configured for a maximum of 2 parallel uploads. This means that if you upload 6 files, only 2 will be uploaded at a time. The rest will be queued and uploaded in order as soon as one of the first 2 uploads finishes.
p.s. The default value for maxParallelUploads is 5. Here we are setting it to 2 just to make it easier to see the queue in action.
