This is really weird and I am not sure which version introduced the problem, but I suddenly can't upload images anymore. Old images work fine and I can also insert them, but as soon as I am uploading a new one it just displays the alternative text.

A quick test shows me that I can load old images by url (e.g. images/stories/...), but new ones give me an HTTP 500 error.

Hopefully, this can be resolved soon.

Thanks,
Jens

After some more research I found that this behavior is caused by images saved in Adobe Photoshop using 32 bits. It appears that I can only display 24 bits in IIS.

I still don't understand why I would get the misleading HTTP 500 and so the problem might be still be somehow related to Joom SEF, but I can now use a workaround by converting images to 24 bits.

I also found that the problem is limited to JPG images.

Hello,

You can try disabling JoomSEF and see whether the images will be displayed correctly to find out whether it's a JoomSEF problem or not.
