Hi Andrius

I know wexactly what you mean.  Yes Id like to know this too. The only way I can think of doing it unless there's an incomedia version is to get a small "wetransfer.com" logo and insert it as a picture onto your site page.

Then add a link to we transfer.com

If you pay them $120 a year you can have your own email and branding and email advice that theres an image waiting for you to download.

I'm about to implement this very thing as Ive been doing image downloads for 13 years!

Good luck
