Made a simple script for you.
Websta.me photo liker:
1. Go to the hashtag feed page.
2. Load as many pages of photos as you want.
3. In Google Chrome, click Ctrl + Shift + C, this will open the console.
4. Paste this code into the console and click Enter:
Code:
!function(){var e=1e3*Math.max(5,parseFloat(prompt("Delay(in seconds) between each like:"))),t=function(){var t=$(".like-icon"),i=0,n=function(){$(t[i]).trigger("click"),i<t.length&&(i++,setTimeout(n,e))};setTimeout(n,500)};setTimeout(t,500)}();
5. A small window should pop up and ask you how long(in seconds) it should wait between each like.
6. The script will now like every photo, one by one. To stop the process, just refresh the page.
Enjoy.
