Cannot enter Settings>Images

[WhoAmI]

In my component view I would like to replace an already existing object with an image. in order to do so i right click the object go to Apperance > Set Alternate Image and select an image i want to use. When selecting, a dialog box appears with the information "Error reading PNG file" (it doesn't matter whether it really is a png file or jpeg). If i go directly into Setting > Images i receive the same message (before even selecting any Image). What might be the reason for this?

Never seen that, but probably someone clobbered the repository. You should remove the image, put in a working copy and change the references to use the new image.
