Yes, you can customize the caption to include anything you need. You can always create a custom markup template, but you can also use the mla_caption parameter to make most kinds of changes to the caption.
You can copy the default “image link” to the caption field by adding this parameter to your [mla_gallery] shortcode:
mla_caption="{+link+}"
The default link includes the thumbnail version of the image, which may not be what you want for a hover effect. You can use the image title instead with this parameter:
mla_caption="<a href='{+link_url+}' title='{+title+}'>{+title+}</a>"
In these examples, values such as {+link+} and {+title+} are a few of the many attachment-specific substitution parameters you can use. Have a look at the “Attachment-specific substitution parameters for the markup template Item part” section on the Settings/Media Library Assistant Documentation tab.
I hope that gets you started on customizing your [mla_gallery] captions. I’m going to mark this issue resolved, but let me know if you have any problems or further questions.
