Hi gnr5,
to be blunt – editing HD Quiz in this way would be far more work than it’s worth (not just coding – it would be computationally expensive to do this too).
However, what version of HD Quiz are you using? There is already a mechanism in place that goes a long way to reducing the complaint you have.
When editing a question, there is a “back to quiz” button. I cannot remember which version exactly I added in this feature, but for a while now, if you click on this button, three things will happen.
The first and obvious thing is that the page loads in the question list for that quiz again. The second is that the previously selected question now has a small indent and a large solid left border to make it visually stand out from the list. The third (which is particularly useful for large page lists) is that the page will automatically scroll to center the previously selected question on the screen.
I know that even with the above, doing what you need to do is… tedious – but I just wanted to let you know about the above in case you never knew or noticed before – especially since doing what you are doing without this would be sooo much worse!
EXTRA:
At the end of the day though, updating 100 or more questions one by one is ALWAYS going to be grind work. Unless you use code. HD Quiz uses attachment_id to store images. Think of it as an “image id”. Whenever you upload an image to WordPress, this ID gets assigned in sequencial order (so first image would be id 10, and the next would be 11, then 12 and so on).
Using this knowledge, if you first uploaded all of your images, we could then create a script that takes a list of question IDs for your quiz and automatically sets the featured image. let me know what you think
