I'm getting a strange behaviour when uploading to the media library recently where Images upload but the pop-up doesn't close and an error is shown if I look in the network tab. The image actually does upload but with no height/width or alt text:

This is the call made to the uploadtarget.aspx page which is returning a 500 error:

> sitecore/shell/applications/flashupload/advanced/uploadtarget.aspx?

This has only just started happening and I'm not sure why as the permissions on the folder seem fine and we haven't updated the code that I can think would affect this recently.

Further info: Sitecore 8.1 update 2.

  • is it specific to one image format? I noticed your example uses a jpeg. I know images can be finicky when saved improperly- this was primarily a problem with Adobe if the image isn't saved for the web. It sounds like the behavior is specific to one environment. I would check the response in Fiddler across a working server vs a failing server. As a last resort, you can reconstruct the processor: <processor mode="on" type="Sitecore.Pipelines.Upload.Save, Sitecore.Kernel" /> inside of the pipeline <uiUpload>.

  • Does it happen with all the images? or just one or two images?

  • It happens on all Images I've tried, including png and gif and also happens on all environments but was all working fine previously. It's odd as I'm not sure what might have affected this. Creating a copy of the image upload pipeline is a good shout though to debug this, I might have to do so if no one has any better ideas. Oct 15, 2016 at 9:53

1 Answer 1


After further investigation it turns out this was an issue with a custom pipeline that was being fired and interfering with the upload of images. We added some logic to skip the pipleline during uploads and it is now working fine.

  • I think you can set your own answer as the correct answer so this drops off the "unanswered" list :) Oct 18, 2016 at 14:24
