Do you supply every single liked photo with a caption or do you treat them more as bookmarks?

Here’s my process. First, I wander around tumblr looking for pictures that pique my interest. That usually takes the longest of the entire process, and I keep track of them by liking them, so yes, as bookmarks. Then, I usually pick ones at random to flesh out as I feel inspired to do so. Not every like gets a caption–sometimes I the reason I liked it in the first place fades.
