The latest from the James Webb Telescope is wonderful, a new look at the “Pillars of Creation”. A photo from 6,500 light years away which you can add to your computer or PowerPoint slide in seconds from the original source.
The image has appeared on many web sites at reduced sizes and resolutions. Far better to get high quality, untampered versions from the original source https://esawebb.org/
Original photo in many sizes
Go here for a range of options for resolution and dimensions of the photo plus narration and technical details.
Look on the right-column for image formats, wallpaper choices or an online zoomable view.
There’s a full size, uncompressed TIF file, all 163MB – way too much for most people.
We grabbed the 2048×1536 wallpaper image which is more than enough for most desktop computers but still only 1.6MB.
The same JPG file should be sufficient for a PowerPoint slide or slide background.
If you’re concerned about the PowerPoint .pptx file size, use one of the smaller wallpaper options or the 1MB ‘screensize JPEG’
