ShareX is a free and open source Windows application that you can use for taking screenshots and then sharing them with others. Starting with version 9.0.0, you can easily upload screenshots to DreamObjects. ShareX takes advantage of the S3 API compatibility of DreamObjects to allow it to be configured as a destination.

To route the destination of the screenshots and other information to DreamObjects, return to the ‘Destinations’ folder option within SharedX.
Select the ‘Image uploader’ > ‘File uploader’ > ‘Amazon S3’ option as shown in the above screenshot.
