Since my site has been updated to 3.4.1 I can't load any pictures "full size" into my articles (broken link).
Affected are only files, which had been added to library using wp 3.4.1.
I am however still able to load all the reduced sizes of the same newly added pictures.
What I discoverd so far is: When I upload a picture with WP 3.4.1, the full-size file in the media folder lacks reading permissions for IIS_IUSRS. All the thumbnails have correct permissions.
After granting reading perms for IIS_IUSRS to the file in the library manually, everything works fine.
Tried changing location of library, disabling plugins etc. etc.
This seems to be a bug.
Any help is greatly appreciated.
