Showcase of an Attendance Tracking Power App

It has been about a year since I posted a blog on new functionality introduced natively to display highly optimised thumbnail renditions / images of photos and / or documents stored in SharePoint Document Libraries leveraging a SharePoint data source connection within Power Apps.

SharePoint Powered Thumbnails Have Arrived in PowerApps!

Seemingly however there is still a misnomer amongst some App Makers in the community that the native functionality to display images of files stored in SharePoint within Power Apps, in particular when running apps on mobile devices, has as yet not been implemented.

The intent behind this follow-up blog is to dispel that myth by showcasing by way of example what type of apps can be created with sublime performance rendering high quality and significant optimized thumbnail images.

First let’s look at the demo of a super awesome Attendance Tracking Power App I have been working on.

Naturally for many App Makers the question no doubt arises with regards to just how effecient thumbnail images depicted in the app showcased in this blog are. The size of the photos displayed in the demo as are stored in SharePoint range from between 60 KB to 20 MB.

All of the photos rendered in the app were equally uploaded to SharePoint from the app, inclusive of a number of photos that are between 10 MB to 20 MB in size. The demo showcases the sublime performance in rendering any photo within the app regardless of size.

By way of example the thumbnail images of a 20 MB photo stored in SharePoint are rendered within the app, as per the following screenshots taken with the Chrome Devtools debug window open monitoring network activity as the thumbails images are rendered within the app.
