The random pics I am talking about are actually on my phone... and are helping me to learn Finnish. I've posted a while ago about some of the things I learned about language learning over the years. One of the things that is a rather new tool for me, and that I enjoy a lot, is getting little images and charts and explanation pics via feeds on Instagram. There's a hashtag that I follow where a lot of these turn up, and if there's an especially helpful one, or funny one, I take a screenshot and save the image.
However, having the stuff is good, but not completely helpful yet - these things will only get more language into my brain if I can actually see them. So I've looked for a smartphone widget that picks random images from a folder and displays them.
There's a few of them in the GPlay app store, but most free ones that I tried had some trouble, or cut off the image if it did not by chance fit the frame, or were otherwise annoying. But a few days ago, by pure chance when looking again, I found one written by a German developer called Zufallsbild. This little thing does exactly what it should - you can select a folder or several folders and have it swap the image after a given time, or swap to the next one yourself. It scales the image to fit into the frame, too. Which means that I'm now very happy, and get to see all the nice and funny things on my phone home screen, one after the other.
So if you're looking for an android app for displaying images on your phone, because just having all those funny or nice or beautiful things is not enough... maybe it's the thing for you, too!
