We are using SDocs with images hosted in Box due to image size constraints.  We are having an issue where the PDF renders VERY quickly, however the images which are hosted on Box do not have time to render before the PDF creation is complete.  Is there a way to slow down the PDF creation process to ensure that the images are rendered prior to the PDF finalization?

This was working for about 2 months, however we're back to this issue after Summer '14 release.  We did find a whitelist issue that was resolved, so the images are not broken, however they also do not show up.

We've updated to SDocs Winter '15 in our sandbox (we do not have a Salesforce Winter '15 instance this time), however that does not solve the issue.  In addition, we're using direct links (non-redirected) to ensure that the images are loaded as quickly as possible.
