Can I cite in a caption? I am using an image from a users’ manual of a piece of software, and I was wondering if I can put a citation in the caption of the image. For example:


  Figure 1.3 Illustration of WonderSoft’s interface. Image taken from WonderSoft’s users’ manual (Bitsmith et al., 1821).
Unless your journal, advisor or institution insist against this (which we cannot know), yes, you can.

I have done this myself in publications and nobody complained.
