If it’s OK, I’m going to bump / re-open this thread instead of starting a new one. I’m having the same issue in IE8 and IE9 (Flash-based uploader); I get the message “Failed to extract images from zip” when trying to upload non-zipped images. If I upload an actual zip file it is extracted correctly, so it seems the problem is just that it’s incorrectly treating image files as zip archives.
Like OP, I do not experience the issue in Firefox or Chrome (which use the HTML5 uploader), the problem seems to be isolated to the Flash uploader.
(I see there are a couple of other reports of the same issue in the forums).
- NextGen Gallery 2.0.40
- WordPress 3.8
- Same issue in multiple server environments (UwAmp 2.2.1 on WinXP; Apache/PHP on Linux, versions unknown but probably irrelevant)
- IE 8 / 9
