I've seen some references to this problem I'm having in the forum, but I don't think it has been resolved. I have a modified Default theme. When I draw a thumbnail page with Search and then use the "Next" button to navigate through the search results, I get the first image from the Search, then go the Next image goes back to my main album (I have only one Published Album). Subsequent "Nexts" are from my main album, not my search results . If i apply the Default theme, it seems to work so it was something I modified on the templates, yet my "gallerytitle" div is straight out of the Default theme.

Well, if it works in the default theme, something is wrong with your own. Sorry, we won't be much able to help with that. You also did not tell what Zenphoto version.

Latest Zenphoto version, of course!
Since it worked with the Default theme, i substituted various Default theme files till I determined the problem was with my image.php, then i worked backwards editing the image.php till my custom theme worked and the Prev/Next also worked. I don't know what i did wrong before -- which is troubling-- but it works now. Thanks.
