This is my go-to screenshot tool on Linux. For Linux users who also use Google Photos already, you may not realize this but the Google Photos web app accepts paste from system clipboard via Ctrl+V in the browser. Thus, my workflow if I want to save a screenshot for later is to call up flameshot in rectangular selection mode (I bind it to the PrtScn key), select my screenshot area, Ctrl+C to copy it to clipboard, navigate to GPhotos web app via address bar / bookmark bar shortcut, and Ctrl+V to upload there. The nice thing about this is that GPhotos recognizes it as a screenshot (so I can find it on my phone later, too, for example). And, GPhotos also automatically indexes any text within the screenshot, so free text search can often find it, too. If I need the screenshot as a file for some other purpose, I'll navigate to it in GPhotos and use Shift+D to download it. I can also use GPhotos to privately share the screenshot with someone via their email address, or get a tokenized link for it. Just sharing this tip because I notice a lot of people hunt around for cloud storage for desktop screenshots. But Google Photos works pretty well for this purpose already, if you use the paste-to-upload trick!
