Redmine

Can't reproduce defect with Chrome. Could you make some more experiments? May it depends on the image size, image format, chrome version, ... ? However displaying big inline images in chrome 26 works for me.

After I go to install an Apache mod mod_pagespeed from https://developers.google.com/speed/pagespeed/mod , the problem is not happened again.

So it seems like a configuration issue of Apache, but i'm still not sure what the root cause is.

Try this:
1) Your mouse cursor shows that the page is loading. Press ESC to break page loading when your inline picture is shown. So now your picture should't disapear. Get the path of this picture. Then reload the page and wait until finished. Get again the path of your picture and compare with first determined path. Are they the same?

2) Load your page and wait until image disapears. Copy the path of picture in url adress field and load this only picture (without any html). Does it work?

3) Do you have this problem also with firefox? In firefox you can use Firebug to analyze the page and html elements.

I can't reproduce this problem even if i remove the mod_pagespeed, restart apache, and clean all cache/cookie from google chrome. But i'm sure it can be reproduced before installing mod_pagespeed.

Hope that someone else who encounter this problem can provide more info in the future.

P.S. the problem has mentioned in bitnami and seems has been fixed in BitNami Redmine 2.1.2-1 http://answers.bitnami.com/questions/8191/redmine-disappearing-inline-images , but i encounter it in redmine 2.2.3 and redmine 2.3(tried to solve it by upgrading to 2.3)

Confirmed the problem is due to Kaspersky + Chrome

The problem is a combination of Kaspersky and Chrome.

Turn off Kaspersky's protection temporarily, and you'll see that the images stay on the page!

I've written to Kaspersky about this, and despite looking, they were unable to pin-point the problem. They only know that it started after a mid-2012 update. Also it happens on KIS, but not on PURE, etc etc.

I will send them a link to this superuser page -- maybe the other answers will help them fix this!

and a workaround http://superuser.com/a/287454 is to remove the "Content-Length" from the header of the image.
