Not just picture. What if I have to submit a report to government agency on government site?
Which government? Which site? What kind of file?
You can upload a RAR file to the government of Namibia's web portal, but not to their Minister of Affairs office. For that office, you can upload a zip, under 12mb. Over 12mb and you must use the Chad embassy's website and request a Namibian transfer, Wednesdays from 11-4 pm GMT. Of course, you will have to upload your credentials in PDF format before you can submit the request. To upload a PDF, you will need VPN access and a Kerberos key, unless you are a DJ, in which case you can convert your PDF to an mp3 at 128kbps, no larger than 6mb.
Seriously. You can come up with a million scenarios for things you are unable to do on any smartphone, period. What is your point?
