Hey all,
I rolled out something last night and into this morning that should have addressed the issue. We had our website reported for phishing, however, we didn't have any actual phishing going on, so I had to work on getting our reputation cleared. I'm going to work on a long term security solution for our image attachments, which will make it impossible for our image attachments to get reported for phishing, when no phishing is actually occurring.
Sorry to get geeky on you all! I really appreciate everyone's patience and support.
If you are still experiencing the issue of seeing no images, please contact me via PM so that I can look into it.
