Just upgraded from 1.4.2 to 1.4.2.1 and I find some icons missing from the gallery page (http://www.ormondhistory.ie/zenphoto/) eg icon for gallery search & icon for RSS feeds. Any ideas ?

the rss icon shows as a not valid image. I could not get at the search one. Try re-uploading the zp-core/images folder

Uploaded the zp-core/images folder again as you suggested but unfortunately things are still the same - many of the icons are missing from the admin pages as well, although the actual links are active.

Maybe there is a problem with your FTP client. Or maybe a problem with the download of the Zenphoto release. The rss icon is definately corrupted. See if you can view it locally.

Just to note, I cannot even access that site currently, "internal server error 500".

Downloaded 1.4.2.1 package again & uploaded complete zp-core directory again. which fixed the problem. Thanks to all for your assistance on this
