If so, use Windows Explorer (Not Internet Explorer) to access the folder where they reside, then click on "Edit" in the upper left, choose "Select All". All the photos in that folder will be highlighted.. Now click on "File" in the upper left, choose "Delete", then click on "Yes/OK" when it asks "Are you sure?". All of the photos will now be sent to the Recycle Bin from which you can them delete them entirely.

As to Skype, they do have a Help site. Click on the links below:

How do I contact Skype customer service for help with my service?

Hope this helps.
