So the steps are:
1. In Google
Chrome, go to www.instagram.com and log
in on your device (assuming that you have an Instagram account on your phone.
2. You'll
notice that there is no way to write a post. So right click on the screen of your Instagram, and in the
window that opens go right down to the bottom and select ‘Inspect’.
3. This opens
an HTML section. Go right to the top and click on the ‘Toggle ‘ icon. (2nd from the
left) You’ll notice that a dot appears
on your screen which is on the left. Go
to ‘Next’ at the top.
4. Refresh the
page. You’ll find that Instagram now
looks like your mobile app except that the + sign is at the bottom instead of
at the top. From here you add your
photo, resize it and add text.
