Hi

I have a way to add alt and title attributes that seems to work.

You will need the str_replace extension function from http://ez.no/developer/contribs/template_plugins/string_replace_operator

Once this is active I then altered ezimage.tpl in (my design folder)/templates/content/datatype/view/ezimage.tpl, adding:

...

{def $image_name_without_hyphens=ezstr_replace('-',' ',$image.basename)}

<img src={$image.url|ezroot} width="{$image.width}" height="{$image.height}" {section show=$hspace}hspace="{$hspace}"{/section} style="border: {$border_size}px;" alt="{$image_name_without_hyphens|wash(xhtml)}" title="{$image_name_without_hyphens|wash(xhtml)}" />

...

This simply uses the name that you give the image when you upload it as the alt and title attributes, having stripped the hyphens that get added to basename out.

This also works for embedded images through the OE editor, but use $image_variation.basename instead for those.

No need for str_replace, the object name is mostly what you specified in the upload dialog or the image name without the file extension anyway:
content/datatype/view/ezimage.tpl

{*
Input:
 image_class - Which image alias to show, default is large
 css_class     - Optional css class to wrap around the <img> tag, the
                 class will be placed in a <div> tag.
 alignment     - How to align the image, use 'left', 'right' or false().
 link_to_image - boolean, if true the url_alias will be fetched and
                 used as link.
 href          - Optional string, if set it will create a <a> tag
                 around the image with href as the link.
 border_size   - Size of border around image, default is 0

Yes, that's a better way

Where would $image.text usually come from? There doesn't seem to be any inputs for this when uploading an image..

Also, I was thinking that it would be even better if there were extra fields for both any caption, the alt text and the title text, instead of taking these all from the name of the image. I could add custom attributes that would apply to all embedded content for image uploads within the OE editor, but how would I do this for images through the template class structure? Only in my image class I have an XML Block called 'Caption' along with another field called 'Tags', yet I don't get a chance to input these when uploading an image.
