I had a problem caused, I believe, by a theme that I have chosen to use. I determined that the best solution was to uninstall then reinstall WordPress. I did that including the chosen theme and the usual set of plugins. That seemed to fix the problem I was having that triggered this whole mess in the first place. I had 3 web pages created to my satisfaction before I had to do the uninstall of WP. I have a backup copy on my local machine hard disk of all my WP folders and files under /public/wordpress using my WS_FTP program before I uninstalled WP. AT the time I made the backup file set there were no problems with WP. So everything I downloaded to my hard disk should be without flaw. Using the same WS_FTP program I uploaded the image files to the exact same folder structure that existed before I uninstalled WP. I'll spare you the details has to how I know that the subdirectory structure was exactly the same as when everything was working OK. But believe me. They are the same. I was able to verify this using FileManagerPro provided by my web hosting company Earthlink.
After reading some problems/solutions in the WP forum, I changed the permissions on all the files and folders to 755 beginning with the "/Upload" directory as was suggested in one of the WP forum entries. This didn't help me one bit even though a respondent in the forum said this fixed this problem for them. I made the permission changes using FileManagerPro provided by my web hosting company Earthlink.
I hope somebody here has a solution that will work for me. I think I may need to acquire "BackupBuddy". Oh! my local environment is Windows 7.
