Visual design bleg: I'd like a header for /r/DecisionTheory but I have no image manipulation skills.

So Reddit lets you add image headers/banners to subreddits to visually sum it up: https://www.reddit.com/wiki/styling#wiki_header_image

> The default header image is 120x40. The modified version can be of any dimension or file size, but is recommended to keep it no wider than 300 and shorter than 100. The file size is strongly recommended to be within 100Kb as not all users have 10MB+ connections.

I summed up decision theory in the sidebar as:

Statistical decision theory is concerned with making optimal decisions under statistical uncertainty, often maximizing expected utility. It can be applied to many areas such as economics, medicine, finance, and business, and draws heavily on Bayesian statistics, meta-analysis, optimization, POMDPs, reinforcement learning, causal modeling, game theory, and operations research. Goals include cost-benefit analyses (calculating expected utility of specific choices), defining relevant loss functions, the value of perfect data and the optimal amount of data to gather, balancing taking (estimated) optimal actions with learning about other suboptimal actions, inferring causal mechanisms in an environment, eliciting expert beliefs for priors, and examining sensitivity of conclusions about decisions to the data or modeling choices.

So I tend to see decision theory as the following workflow: meta-analysis -> Bayesian estimation of effects -> decision tree/POMPD -> action.

There are images covering the 3 steps; for example:

- https://community.cochrane.org/sites/default/files/uploads/images/cclogo-big-trans.gif (the Cochrane Logo is a paradigmatic case for the benefits of meta-analysis, and the forest plot tells a tragic story; would need to erase the non-forest-plot parts though)

- Bayesian search theory, which is based on decision theory, offers some nice visuals as well, like posterior probability plots from the Air France 447 search (eg http://blogs.sas.com/content/subconsciousmusings/files/2014/04/af447_posterior1.jpg ) and might be used as the final image in a montage?

If someone wanted to edit these and fuse them into a nice-looking Reddit header, or come up with some even better, I'd appreciate it. If not, no big deal; I might look into a service like Fiverr or something.
