Unlike some other apps I saw suggested from Firefox & others results from Apps search & Google search this 1 actually was to UPLOAD images to certain sites like Instagram (90% of the others were to download images already posted on sites by other people instead of using screenshot apps, almost complete opposite of what I was searching for). And even better you explained how it works & how to use it RIGHT in certain internet servers. That helped a lot more than what I got from Google (lol. Some results were even outdated/impossible to use now). This saved me time & even money because now I don't have to go buy a smartphone just to actually/fully use a website (or 2+).
