Easiest suggestion would be to install either the tapatalk or forum runner apps from the play store, there is a free version, but it does have ads. I use the paid version of Tapatalk. As for using file upload from the web page in your web browser, it typically will show some the supported apps on your device to browse for files on your device, that will be specific to your device and I don't know which ones you have to suggest one, also may depend on the web browser you're using. I'm using the chrome browser on my phone and it doesn't even come up with any that will browse my local files to attach, so I'll have to do some research to see which apps are supported for browsing local files from it and report back here.
