can we make uploads into cloud storage using html5

Answer 1

You can't. HTML's only purpose is to define the STATIC CONTENT of a webpage. HTML cannot DO anything. For file uploads, you'll need server side code, such as PHP.

Answer 2

If your cloud provider provider direct link of images then yes. Example in forums for signatures most people dont upload pics to that forum, they use direct links.

In simple words,
If u get a direct link from your cloud server which entering in browser shows you image only then put that link in <img src=""......i hope you understood what i mean.
