Thank you for your purchase.
I will try to answer your questions:
- there is no default image in case an image is missing. I can see this option as a good addition to the module and I will make sure this is included in the next release.
- titles for K2 items should show. Make sure this is not a problem with the template's CSS. Articles are included in h2 tags. Also, titles do not show if item options set the titles to 'hide'.
- the slider's purpose is to create slideshows with article/item contents to be the content of the slide. A slide can definitely link to itself or to another article. A module like 'Latest News Enhanced Extended' is a better fit if you need a slide to be a summary of a larger article. If Truly Responsive Slider does not correspond to your needs, I have a 30 days refund policy.
- categories can be visible or not, depending on the items' parameters, the same way titles are.
