Just to make this clear - are the files hosted on your platform, or on dropbox? And what are the limits of your free accounts (if any)?

I see your site says you offer hosting - but I am getting confused a bit as there is no complete feature list on your website - just lengthy documentation.

Do you have some traffic limits?

Do you have bandwidth cap/space cap?

Are pictures etc. hosted on dropbox or your servers?

Congrats on front page and good luck!
