Image Search is dropping the hyphen from file name

I am not sure the search results problem with or without Hyphen "-" is the only thing concerning these "Hyphens" thats going wrong. Thats why Im adding my remark for the first time to a google thread.
Searching for the reasons why my sites (journalists articles and fotos on various topics) have major losses in the last weeks I came across something weird that might just be part of an iceberg concerning these "-".

My example (I hope I can make it clear):
I have a picture on number 1 position with a very common term on google images. When you click the picture, normally the exact page where the picture was found should appear in the bottom section of the new window. What happens is: it doesnt show that exact page but my index page instead. The reason: The "Hyphen" or "-" in the name of that "underpage" has been left out when being processed by google which can be seen as the link shown by google in the upper part is wrong (lacking the hyphens). Therefor the search has acutally turned up with an error.

Sorry, if this is nonsense or irrelevant for you more experienced guys, but to my little brain this seems to be an extension of your discussed problem with the "Hyphen" that might reach far into all sites with "hyphened-pages-on-the-web".

That is one interesting bug -- why would the hyphen in the page's file name be dropped? It can't be intentional, so it sounds like a sign of some coding problem on the back end with regard to hyphens. I'm off to check for other examples.
