I've got some automatic emails that are sent out upon signup completion for my site.
Until recently, they worked fine. Now Google's new system is rewriting the images and storing them in it's cache (supposedly)
However, Google's new rewriting of my image links are completely breaking them, giving a 500 error and a broken link image.
Lets say my normal image url is:
http://www.mysite.com/images/pic1.jpg
Google is rewriting this to:
https://ci5.googleusercontent.com/proxy/vI79kajdUGm6Wk-fjyicDLjZbCB1w9NfkoZ-zQFOB2OpJ1ILmSvfvHmE56r72us5mIuIXCFiO3V8rgkZOjfhghTH0R07BbcQy5g=s0-d-e1-ft#http://www.mysite.com/images/pic1.jpg
However, there is nothing at that URL.
So, either there is something wrong with the links that are being created by Google or the images are just not being uploaded to the googleusercontent server, but I have no idea how to solve the issue.
Im using PHP, the phpmailer library and a Ubuntu server on Amazon EC2, but Im not sure that is related to the issue.
I had this issue when I was sending gifs. I found that the file size matters to Googles Proxy server. I suggest making the files as small as possible and see if that works. You can use your Gmail account and add a photo from a URL to test. If the gif shows up when you are composing your email it will be receivable.
happy coding.
It's March 6 and you've probably already figured this out, but thought I'd chime in to help others. I discovered that JPGs don't work in gmail. The PNG format works great. Sorry I can't explain why, but sometimes it's better not to ask why. Use PNG!
Based on your example, it looks like you are using traditional extensions (.jpg, .png, .gif). Some folks on this thread, describing the same issues you are facing, have stated that using those extensions solves the problem.
