comment Cannot change ImageResolution after applying ImagePad
I think you have confused yourself slightly by referring to Graphics expressions as images. Your tempimage is not an Image, it is a Graphics expression. As Alexey notes, when ImagePad receives an argument which is not already an Image it must rasterize it. This rasterization takes place behind the scenes, using default settings. As you have discovered, if the default settings are no good for you, you need to do the rasterization explicitly with your preferred settings instead of having ImagePad do it automatically.

comment How combine pure functions of several slots?
Would a replacement based approach work for you, e.g. thru[expr_[vars__]] := expr /. f_Function :> f[vars]

comment Programmatic approach to HDR photography with Mathematica image processing functions
@belisarius, thanks. I think this must have been updated in version 9. CreateHDRI and ToneMapHDR seem to be working nicely now.

comment johansen test error in code
There is a version of this code on @Verbeia 's website, using the old AppendRows function. I think this should be replaced with Join[##,2]& rather than just Join.

comment Behavior of Graphics`Mesh`InPolygonQ with self-intersecting polygons
@Avi, I think the winding number must always increase or decrease by 1 when you cross the polygon boundary, so holes will always have an even winding number.

comment Replace inside a Held expression separate context
@Liam, if that's a problem why not just strip out the Defer with a replacement /. Defer[x_] :> x
