That's how I'd do it. In fact, I have a commercial client product that 
does exactly that. Make sure you set the lockLoc of each image object to 
true so it won't auto-resize when you set its content.

Lock the screen, set the image filename, get the formattedheight and 
formattedwidth of the image, and then write a function to get the 
smallest ratio that will fit. Apply that ratio to the horiztonal and 
vertical dimensions and then set the size of the image to the new 
dimensions.

You can show as many images in a field as you want, but I wouldn't even 
consider this approach. You'd still need invisible dummy images on the 
card to serve as the source material, you'd still need to resize them to 
fit into the dimensions you want to display, and then after all that 
you'd need to add an additional step to insert them into the field. 
There's no reason not to just display the images themselves in a 
scrolling group.
