I've got tapatalk installed on this phone. I just prefer to use a browser to visit this site. But I may have to break down and use tapatalk for uploading pictures.
I just tried using the "request desktop site" function in Firefox, and while it does, then, display the controls to let you insert a picture or video, etc., I tried to get it done, and failed because the pop-up that let's you select and upload or link to an image can't be positioned such that you can actually use it. Even using the S-Pen and trying to get the job done with it displayed very tiny didn't work.
It's pretty ironic that a site dedicated to Android devices isn't set up to let us access all of the features without installing a separate app on our Android devices. But it works fine from a desktop or laptop PC.
I may try using tapatalk, but I don't really like it in general because you don't see all of what is on the website the way you do when visiting using a browser.
I wonder what most people do to share their photos here. Are you all using Tapatalk?
