I'm trying to figure out how to stop the full-size image from showing in another blank window. I want the image to show in the window that gives you the option to click "show details" instead of the small thumbnail.
Does anyone know how to do the following, I think this is what I'm trying to do.
As for you second suggestion, this is entirely possible and probably really simple to implement. You'll notice that clicking on a thumbnail on the manage page does exactly what you describe. You can go into gallery.php and manually change the picture level links to match these javascript popup links. You will have to copy plog-thumbpopup.php to your Plogger root directory, and maybe some JS code, but I imagine if you have even a basic familiarity with coding you should be able to do this with no problem.
Again, thanks for your suggestions and kind works. Good luck!
