imbedded alert graphs missing in alert emails using outlook / gmail
Hello,
I'm aware that the imbedded image problem has been discussed on here previously. I believe the final answer was "outlook sucks". Both outlook and Gmail web are unable to display the images, but my android email application works. I asked one of our support guys to take a peak and help shed some light on the matter. According to him, it might boil down to using a cid tag instead of a data tag to imbed the image.
I have no idea what that means, but hopefully it will help an intelligent developer. Thanks for any and all help into this matter. I'd love to see graphs in my alerts!
I've included his email below for additional details: ------ The specific image in question that is not loading is embedded as a base64 encoded image, with a data tag instead of cid tag for the source URL in the message source. Outlook uses Word for composing and displaying emails, and apparently Word does not support the method by which the png file was embedded, as it does not use a cid tag. The PNG format itself is not the issue, because I was able to acquire the original image, paste it into a new email in Outlook, and send it to myself, and it shows up just fine. Looking at the source in that scenario, the PNG source is using a cid tag.
I'm uncertain how the message in question is being generated, and whether the method by which it's embedding the image can be altered, but ultimately it seems like the current method is unsupported by Outlook/Word, and I have not yet found any good fixes or workarounds, other than to change the embedding method, or to run a command in Outlook that will open the email in a web browser, which will then display the image in question.

Fixing it requires rewriting a few functions to handle passing around and attaching images.
It's not going to happen anytime soon, I think.
