Placing 2 images on a slide at same distance away from left and right edge

You don't need anything to help you with positioning an object a given distance from the left side.  Just select the object, go to Properties > Transform and set X to whatever spacing you wanted.

For the right side, I just dump a highlight box on screen, set it's width to the number of pixels I need for the spacing and then move my other object's edge over until it just touches the left edge of my spacer.  Afterward, delete your spacer or just drag it off into the scrap area so that it doesn't get published.

All of this only takes a couple of moments to accomplish.

Hi Noel,

It would be great if one could group those two objects and then center them horizontally on the slide, but another feature request I'm waiting for having it available finally

You have to know that aligning,moving, resizing is always starting from the registration point, which is the top left point of the bounding box of the object. Those coordinates are in the X/Y in the Transform accoridion of its properties. In that same accordion you have the width of the object (again width of the bounding box). So you'll need to do some maths, sorry:

One example= if the resolution of the slide is 800x600, and the width of your rectangles is 120pixels, you need a X-coordinate of : 800 - 120 - 139 = 541

Or another way (but not when you already have 139px fixed:

Put left object at coordinate X=0, then use shortcut SHIFT-RIGHT to move it 10px to the right or CTRL-RIGHT to move it 16px (hope it is correct, no CP here) to the right. Put the right object at X-widtht of the object and move it the same number of clicks to the left with the same shortcuts as the left object.
