Divide frame into multiple frames?

Scott, love your Illy solution. I'm partial to "Divide Objects Below".

With Adobe there is always more than one way to skin a cat.

Illustrator:

Filled color rectangle.

Line Tool, draw some overlapping Stroked lines.

Live Paint, Fill paint.

Expand Live Paint. Delete Grouped Strokes.

If you want spaces between Shapes, Effect>Path>Offset paths is your friend here.

Expand Appearances and copy and paste into your InD document.

InDesign:

Copy and Paste

Use each close path as your Clipping Mask.

Drag and drop your photos into.

Resize/Rotate as you wish.

One and Done.

There's no Divide command in InDesign.

As far as I can see, Obi's method is pretty much the same as mine, just illustrated. Maybe all the process could be fastened by the script, I dunno. Or maybe Obi will correct me.

And about what lines you're talking? There's no lines left, whatever method you use.

… So easy to do it in InDesign! 

… and so perfect!

Thanks for all of your help!

Scott Falkner's answer works great but how do I delete the lines when i'm done placing images?

I think it's easier to use stacking rather than Pathfinder operations here. Draw overlapping shapes, give them a stroke, and send them back and forward accordingly.

Sure, Illustrator is the right tool for this kind of job. But this is an InDesign forum, and what if you don't have Illy installed?

You still can mimic almost the same workflow just in place. Two main differences:

1. Instead of lines, use thin, lines-like rectangles. Place them over the "main" rectangle as you would place the lines in Illy. Select All, open the Pathfinder panel, click Subtract (subtracts the frontmost objects from the backmost object). You'll get a rectangle, divided into pieces. However, it's still the one object - a path, divided in segments.

2. Select each segment one-by-one (with Direct Selection Tool, Alt+click on a anchor point). All anchor points of the segment will be selected. Cut it and Paste In Place. Now it's a separate path/object. Repeat this with every segment, except the last one.

You're done.

Another, completely different approach - using Document Grid with enabled Snap to Grid. Just draw several figures of desired shape, snap them to each other using Direct Selection Tool and Document Grid.
