问题： I have a Flash project, and it has many source files. 我有一个Flash项目，它有很多源文件。 I have a fairly heavily-used class, call it Jenine. 我有一个相当频繁使用的课程，称之为Jenine。 I recently (and, perhaps, callously) relocated Jenine from one namespace to another. 我最近（也许，无情地）将Jenine从一个名称空间重新定位到另一个名称空间。 I thought we were ready - I thought it was time. 我以为我们已经准备好了 - 我以为是时候了。 The new Jenine was better in every way - she had lost some code bloat, she had decoupled herself from a few vestigial class relationships, and she had finally come home to the namespace that she had always secretly known in her heart was the one

Everything works just fine, except that after I create a post in production and attach an image, the image stops showing after a while (say 30 minutes). I scouted around the internet looking for solutions and saw this which suggest the problem has to do with Heroku wiping the directory after every app restart. One solution offered is to host your images on a service like Amazon S3. I have however set S3 up and the images are being sent to the
