Welcome to the vMix Forums!
I would explore options with the "MultiView" Feature (or as I prefer to call it "multilayer").
Different sized images might pose a bit of a challenge if you want them all to be more or less standardized, but that is the simplest and most direct method to do what you describe.

You don't need 30 Inputs, just one Photos Input.

Add a Picture Input with your background image (*).
Add a Color Input (select Transparent) which will be your "template". Change it to use your background image as MultiView layer 1.
Put all images in one Windows folder. Add a Photos Input, using that folder as its source.
Use the Photos Input as a source for the second MultiView layer in your template, adjusting size and position
Create your frame as a transparent png, with only the frame, use an Input with it as the third layer
Add your camera as the fourth layer in the template (adjusting its size and position to fit in the frame)

Yes, you can use X-keys (or a small midi board) and the shortcuts NextPicture and PreviousPicture to step through the images in your Photos input.

As Ice mentions, diferrent image sizes might cause a problem. But VMix will scale them to fit, keeping aspect ratio if you select the Input's Aspect ratio as "Source".


(* you could build your template on this Input, but having it separate makes it easier to change the background if you wanna do that later on)
