Scenario Block Image Compression
I'm on a very fast internet connection, but noticed when testing a clients Rise360 course that there was a flicker when new character images loaded. As an experiment I created a scenario in a Rise course and published it, just so I could check the image output for the characters. I gathered all of the character assets into a single folder, and it is 12.4mb for 12 characters. Just over 1mb each. This seems really large for a PNG asset, even with transparency. I experimented running the images through TinyPNG, just one pass, and the output reduced the size to a total of 2.91mb. An average of 0.24mb, which is 1/4 of the original size, without any visible loss in quality. I think this is significant to look at, as we would expect the assets that are bundled with courses to be optimised for our users. This should be JS, CSS and any other assets in the course so that it is as quick as possible to download, especially for mobile. If anybody is interested in seeing the difference, I am including the before and after images as an attachment on this post. Edit:Attachments don't appear to be working for posts.
