Random image from Specific Album?

Ok I don’t know if this would be the better way but I solved my problem.
I needed to fetch a random image within a specific album.
Here is what I’ve done:

1. Created a new instance called album_number and added it to the update and widget functions.
2. Created a new input field with number value, called album_number.
3. Replaced $selected_album = $data[array_rand($data)]; with $data[$album_number];

That’s it, I am now able to select my specific album, the only thing is I am having trouble identifying my albums, I suppose they are stored in order of creation, So I had to guess mine was album number 3.

I hope this helps anyone looking to do anything similar.
Cheers,
Jay!
