So, do you ever get email with images that need to be loaded because they are not or not properly attached to the email? I do, and I have to say I don't really like it. Of course, there is the trade-off that the email size will increase if they are attached to the email, but if the sender takes care the number and size of the images are small and therefor the size of the email should still be at an acceptable level.

While writing the unit tests for our new extension EmailImages we discovered that there was no easy way in Ecomdev_PHPUnit (or at least no documented way) to enable the use of the cache. It seemed it would only work without the cache enabled. Since our module caches images that were downloaded to be attached to an email, we would like to at least use the unit test to get 100% code coverage and to see in the log file that the cache was actually being used for these images. (Of course it would be better to have that part included in the unit test itself, but we'll leave that as an exercise to the reader, please submit your input!)
