Hi, I have installed plogger at my dev server and testing it for usability. My boss wants it to display single latest photograph at home page (along with exif, comments etc) and collections below it.
There are some plugins available in the Administration screen tabs. Not exactly what you are describing, but maybe you could adapt the code from them to achieve what you want.
Just make a SQL select on your page which grabs the photo with the most recent date, as the date uploaded to your gallery is stored, just use that field sort the photos based on it, build the array, and return only 1 result, that result will be the most recent. Then copy the picture.php fields of the exif info you want and past that on your homepage too.
