Good work, but I don't like how all the images are forced to 1:1 ratio. You should try to preserve the original aspect ratio. You could either choose a width and that way you can have a certain # of columns with images running down vertically. Or choose a height and have them running left to right in rows of equal height.
Yeah... it's not great but it was on purpose. Some images are crazy dimensions like 300px wide and 5000px tall so it's kind of tough to handle. I guess I could write some logic to preserve the aspect ratio up to a certain point. I do like the nice perfect square of images though.
Cool, I haven't seen that before.
The tech is pretty simple, it's ruby on rails, and a cron job grabs the RSS feed for the Reddit home page, then downloads all of the posts that link to images hosted on imgur. The images are all uploaded to Amazon S3 and the server is on a free Heroku plan.
The next feature I plan to add is a link back to the Reddit comments for each image.
I did find out that if imgur will block you if you retrieve too many images too fast.
Most embarrassing moment of the day was realizing I had (1) already seen all of those photos on Reddit and (2) already forgotten the context to half of them.
