Murray,

Thanks for your suggestion.

So how would I use Row[], ImageSize and Spacer[] to implement myShow[] which simply displays the circles (at the correct sizes) side-by-side with a fixed gap?

showObj[z_]:=Graphics[{Circle[{z,z},z]}]
objs=showObj/@Range[5];

Show[objs]
myShow[objs]

How about just plain Row, and if needed, control the size of each
graphics object in that row by using Show[...., ImageSize -> ... ]. For
example:

    rose = Import["ExampleData/rose.gif"];
    shuttle = ExampleData[{"Geometry3D", "SpaceShuttle"}];

    Row[{Show[rose, ImageSize -> 100], Show[shuttle, ImageSize -> 200]}]

You can insert space between objects in a Row, if you wish, using Spacer.
