Img Alt not changeable for Picasa

Hello. I have PG category imported from Picasa. And now, I need to show in image's alt value the description as set in Picasa. I change alt_value parameter to = 2 (PG control panel > Parameters > Alt value = description).
But, instead description it shows me in img alt the Title. In category with "local" PG images all OK. Problem only in picasa's category. All data successfully imported from Picasa, I check it in DB via SQL.
Help, please.
----
In "views\category\view.html.php" I found output string
Code: Select all
$altValue = PhocaGalleryRenderFront::getAltValue($tmpl['altvalue'], $items[$iS]->title, $items[$iS]->description, $items[$iS]->metadesc);
Echo in picasa category show me:
Code: Select all
altvalue=2, title="File Name 1.jpg", description="File Name 1.jpg" alias="ImageName1jpg" metadesc=""
I.e. description=title. But in database for this image I have description = "My description 1".
Next I trace to
Maybe something wrong in model...

Hi, I will take a look at this, Picasa has no title and description - only caption, so maybe this is why this works this way. I will do some tests (to take into account when the description is added to Picasa images)

I run phpmyadmin and check table *_phocagallery. In "description" field I can see the description text, what I see just under the image in Picasa (<textarea name="description"...). And in "title" field I see Picasa's file name.
As I find In "administrator\components\com_phocagallery\models\phocagalleryc.php":
Code: Select all
function picasaimages
...
$dataImg[$i]['title'] = $value->title->{$Ot};
$dataImg[$i]['description'] = $value->summary->{$Ot};
Data load from Picasa work good, I think...

Hi, still didn't find to test it, I think, the problem can be in outputing images - there is if clause where standard images get standard function and picasa images not
components/com_phocagallery/views/category/tmpl/default_images.php
maybe this one:
Code: Select all
// IMG Start
if ($extImage) {
echo JHtml::_( 'image', $value->extm, $value->altvalue, array('width' => $correctImageRes['width'], 'height' => $correctImageRes['height'], 'class' => 'pg-image'));
} else {
echo JHtml::_( 'image', $value->linkthumbnailpath, $value->oimgalt, array('class' => $value->ooverlibclass ));
}

Thanks! fixed... but I don't remember how to fix it
I have some "efficiency suggestion" instead
1) always cut altvalue before display (PhocaGalleryText::wordDelete) and may be optionally use longdesc (see
http://www.washington.edu/accessit/articles?1257 and
http://www.456bereastreet.com/archive/2 ... ttributes/).
2) make image popup's <a title=... value changeable via "PG control panel > Parameters > Alt value" (perfect - via another option).
I.e. change com_phocagallery\views\category\tmpl\default.php
Code: Select all
if ($value->type == 2) {
if ($value->overlib == 0) {
echo ' title="'. $value->title.'"';
}
}
to
Code: Select all
if ($value->type == 2) {
if ($value->overlib == 0) {
echo ' title="'. $value->altvalue.'"'; //replace title
}
}

Hi, thank you for the ideas, but it is not so easy as it seems, as alt have specific function for specific popups, etc.
