[QUESTION] How to Post image with link in caption clickable in dashboard ?

Hi all,

When I try to put an image with a link in a post. I always end with a post that has a polaroid icon, or with a rectangle that has a text that says "external image". But the image is not displayed. Just the link.

I mean this Icon:



And this kind of boxes:



But I have recently saw posts in my dashboard from post of users i'm following that have animated images (gifs) in the caption that are clickable. These posts were reblogs of video posts. They look like this:



Anyone who know how to post gifs like this one with links that are visible / clickable in when they appear in dashboard results ?

Thanks

I tried to do it. But when I create the reblog but the image has no link... Tumblr strip links from captions. So how they did it ?



I've found more posts...



¿ How can we do something like that ?
.

Where does the clickthrough go to? Offer or Tumblr page?

Sorry for the delay... I've been very busy.

The clickthrough was pointed to a bit.y url that was redirected to a domain thats was also redirected to an offer.
