Hi all,

is there any way to assign tag to a, let's say, 100 of photos in one time? The same question for description/copyright and other fields.

There is no function/option for that on Zenphoto. But two way basically:
1. Use an image program to add EXIF/IPTC data to your images via batch processing. Zenphoto will read this.
2. You can of course do this also directly in the database.

acrylia, thanks. I'm learning the Zenphoto and like it a lot, including the code itself. And I really need this feature, so, perhaps the best way is to write an own plugin for that.

Yes, a plugin is a good idea. Take a look at the "utilities" for the backend.

With the development build (and 1.2.6) there is a plugin that lets you mass-edit images. You have to change each image, but you get them all on one page.

sbillard, thank you, I'll take a look on it.

sbillard, I took the mass edit plugin as a template and made the plugin I talked about.

A quick description - all images(thumbs) from the album are displayed on the one page, without paginating. User can select multiplie images using checkboxes in two clicks - using regular shift-key and ctrl-key modifiers. So you can select/unselect a lot of images very quickly. Check/Uncheck all button is also available.
Images are displayed in small size(even smaller the default thumbnail's size), but on mouse hover the bigger image(500px) is displayed in popup(CSS/JS). The big image is loaded dynamically only on hover, and not on the page initial load, saving traffic.
Once selected, you can choose what you want to bulk change - for now only 'title' and 'description' fields are supported. I don't need other fields, but it's easy to add another fields if someone need to.

So, I wrote the plugin for my needs, and I'm pretty sure it's not ready to be a official plugin - it needs more code cleanup/review, adding more fields and logic, perhaps some redesign. And if someone needs such a plugin - I'll be glad to hear suggestions/requests and also be glad if some will pick up and improve the plugin to make it ready for official approving.

Looks very good !! Hope this will be an official plugin.
I more or less thought sbillard was working on something like this(no offence Stephen)

Looks nice. We always appreciate solutions that evolve from personal needs..:-) (I actually did Zenpage because of that..) You hopefully tested this with the RC2?

We generally do not add third party plugins to the package as official ones anymore as our resources as a small team are a little too limited to maintain those also. We made that "mistake" once before... Except we decide otherwise of course but I will leave that to sbillard.

But if not we will gladly add a entry on our extensions page.

acrylian, I tested it with the 1.2.6 RC1, but will check the RC2 this weekend.

Talking about including plugin I didn't mean to include it into the core tarball, of course - it's up to you, how to store and manage the plugins. I just wonder which criteria the plugin must pass to be listed in the official plugins list. And I also do want that some jQuery-wizard(and also php-wizard and design-wizard ) took a look on the plugin and at least told me weak sides.

And - the final question - which fields must be available for bulk edit? All of the image's fields?

Generally we will not include plugins in the distribution unless we are perpaired to support them. We've had some problems with including plugins and finding the person who developed them has gone inactive leaving problems unresolved.

We are quite happy to post any and all user developed plugins on the WEB pages, though. Then any one can use them (of course if they have issues/questions, they can only be addressed by the developer of the plugin.)

I'm not sure what your last question means. But I think the answer is that you need provide only those fields you wish to handle. Just be sure that the POST processing code matches handling of the fields with the ones that are in the form.

Exactly, we actually add every third party solution we get to know about. Official plugins, meaning those included in the package, are labeld specifially.

@divan: I would like to suggest that you maybe create a small page for that plugin that we can link to when you think it is ready. We can link to this thread but a page would be nicer..:-)

Sreenshots are very nice, this is the feature i want! thanks, great effort!

@acryllian, ok. I'll do it ASAP and will post the link here.

I have for now added an entry on our plugins page linking to this thread so that it does not get lost.

Any update on this plugin?

Have you tried the mass-edit plugin?

Yes, I tried Mass edit, i have to enter details for each photo, but what i need, i can able to select some images/albums and the enter details once & update.

You can download a version of the bulk edit plugin on top of this thread.
