hi,

is there any plugin to display the minimal information of the user with a image he/she uploaded on the gallery.Like a photo displays a line "photo by" somewhere with it.If not then how should i proceed to perform it manually .

regards

Probably no such plugin. Even if there were it would require you to add it to the theme you are using. Presuming you are describing users uploading the image from the Zenphoto upload facility than what you want is to display the "owner" field of the object. Please review the Zenphoto themeing guide and the object model for details.
