Efforts at uncovering “global” metadata feature for images in Joomla CMS


I’ve worked a bit on the problem of copyright information and haven’t gotten far on the specific issue concerning copyright information display in the rotating banner.

However, I did confirm a way to add alternative text / title text without necessarily modifying the HTML code. It might make adding meta tags less painful for new images, but will likely not be that helpful in minimizing the pain of adding meta tags to existing images. And, the change is not "global."

Below are my notes on what I looked at today, plus possible next steps:

Click "Image" directly below "Article Manager: Edit Article."


Directory: /stories/documents

Double click on ‘terrapinpic.jpg’

Set Image Description

Diamondback terrapin [Copyright: J.D. Willson, used with permission]

Set Image Title

Malaclemys terrapin [Copyright: J.D. Willson]

Sceen capture taken.

Click "Inset" button.

Code Changes to Below:

<img src="images/stories/documents/terrapinpic.jpg" alt="Diamondback terrapin [Copyright: J.D. Willson, used with permission]" title="Malaclemys terrapin [Copyright: J.D. Willson]" /><h2>&nbsp;</h2>
<p><strong><img style="float: right;" src="images/stories/documents/terrapinpic.jpg" alt="J.D. Willson" width="200" height="150" /></strong></p>
<p><a href="images/stories/documents/Diamondback_Terrapin_Educators_Guide.pdf"><strong>Diamondback Terrapin Educators Guide</strong></a></p>
<p><a href="images/stories/documents/Diamondback_Terrapin_Living_on_the_Edge_Board_Game.pdf"><strong>Diamondback Terrapin Living on the Edge Board Game</strong></a></p>

Refreshed page:

Confirmed that "on hover" works in:


Checked under "Media Manager"

Navigated to Documents
Selected check box for terrapin image

Clicked "Options" – this was a dead end, options for the folder.

Searched Google for ""media manager" AND metadata AND joomla"


"There are other places where the media manager plays a role, like in categories. It is possible to link an image to a category (Figure 7)."

This might be a way of associating images.

For example, could there be a "Private" And "Joe Farah" category, where any image from Joe Farah is added?

I am hesitant to create a new category without fully understanding the settings for categories. All existing categories <http://www.parcplace.org/administrator/index.php?option=com_categories&view=categories> are public.

I used the existing "uncategorized" category:

Added this to "toggle text"

Images Copyright Joe Farah, used with permission.

Added this to "meta description"
Images donated for use by PARC by Joe Farah.

Under "Basic options" i added the collard lizard.

I also added a note: "Note: Image Copyright Joe Farah."

"photography, copyright" to "Meta Keywords" and "Joe Farah" to Author.

This did not appear to have any effect on the image.

I am also not sure if adding meta tags to the image as it appears at <http://www.parcplace.org/news-a-events/parc-receives-tws-award.html> would impact the appearance of copyright information in the rotating banner on the home screen.

Location of image on TWS award page:

URL for image on pac home page:

For the banner images, J.D. might be right to pursue a CSS solution.

However, I don’t think it is possible to associate metadata with an image on a "global" basis within Joomla. It might be worth posting to a joomla discussion board this problem of "global metadata for an image" or more simply put, write metadata once that appears anywhere the image is used.

Is there anyone who might be knowledgeable about a good Joomla discussion board? I don’t mind to look for one if not.
