Hi,
I'm sorry but this not a solution.
The Full image is taken from Helix Blog Options Featured Image if it is set while it is taken from Joomla Images and Links Full Article Image if Helix Blog Options Featured Image is not set.
In other words, Helix Blog Options Featured Image overrides Joomla Images and Links Full Article Image and this is correct.
The same behaviour should be be implemented for Full Article Image's Image Description (Alt Text).
There's no sense in using Joomla Images and Links Full Article Image paired with Helix Blog Options image Alt Text. Am I wrong?
Also, in all the sites I manage, there are hundreds of articles with Joomla Images and Links Full Article Image and Full Article Image's Image Description (Alt Text) set, with empty Helix Blog Options. Do I have to ask my customers to manually edit all their articles?
Helix has only to ovverride Full Article Image's Image Description (Alt Text) with Helix Blog Options image Alt Text only if this last one is set, just like it does with full article images.
Thanks
