Hi I would like to create photoblog page in zenphoto.
I want to have on one page, from the top to bottom, newest photos with titles, descriptions, comments etc...
Photos must be in full size not thumbs.
I think the best way will be to change archive page. Could anyone can halep me what functions to use. Please remember that I am very rookie in php.
Regards

So are you talking about the full size or the sized images? There is a difference (see the glossary on the user guide).

If you don't know much PHP the easiest is actually to use Zenpage and enable the CombiNews feature. This will "post" newly uploaded images to the news section. They are no real news articles but just mixed between them as if they were.

Take a look at the example here: http://zenpage.maltem.de

Thanks again for help I've created photoblog here:

Is there a possibility to add comments by users to photos in Combinews ?

The CombiNews entries link to the actual image page on the gallery where you can of course also add comments. I have not tried if it is possible to get the comment form working on the new loop directly.
