Dear Tom,
I’ve double-checked on my machine – the videos on your website are re-scaling according to screen resolution as they are supposed to, please see this screenshot for an example.
I must admit, however, that the image resizing issue is my fault. I did not include a responsive styling scenario for images inserted into posts or pages “by hand”: when using the built-in native image uploader, WordPress always gives a class to the image, which was the basis for the existing styling. Please download the updated lessframework.css file here and upload into your theme folder via ftp, replacing the existing file. Thank you for reporting this bug, I will also add the fix to the next release of Origami (version 1.1).
Sincerely,
Andrew | Satori
