Patch #3534
closed
Mask image/x-png as image/png
0%
Description
Internet Explorer uploads PNG files with content type image/x-png, while the official content type is image/png. This is no big deal but Google Chrome doesn't interpret image/x-png as a PNG image and downloads it as if it were an octet stream.
A proposed patch is attached. I've modified the attachments controller to report image/x-png as image/png when serving attachments so that Chrome correctly shows the image inline.
This code could also have gone into the upload part, but I felt it was a bad idea to modify the database for this. There's a test included but I couldn't easily get the tests to run so it is untested.
Based on trunk r2792.

I can confirm this bug and it is still present. I also didn't understand why it didn't happen in my local Redmine instance but it happened on production but now I see that the reason is that IE8 is being used by the reporter, thanks!

To reproduce this, just attach a PNG image using IE8 and try to click on it on Chrome and it will ask you to download it instead of displaying it.
