Joe,
You
can place any number of JPEG images (or grid files for that matter) into a
single aggregate, which is treated as a single group. The following code
from GRIDIMG4 GX illustrates how to do this for 4
images:
// --- create aggregate
---
Agg = Create_AGG();
// --- add grids to the agg ---
LayerIMG_AGG(Agg,sGrid1,iZone,sColor1,rDUMMY);
LayerIMG_AGG(Agg,sGrid2,iZone,sColor2,rDUMMY);
LayerIMG_AGG(Agg,sGrid3,iZone,sColor3,rDUMMY);
LayerIMG_AGG(Agg,sGrid4,iZone,sColor4,rDUMMY);
LayerIMG_AGG(Agg,sGrid2,iZone,sColor2,rDUMMY);
LayerIMG_AGG(Agg,sGrid3,iZone,sColor3,rDUMMY);
LayerIMG_AGG(Agg,sGrid4,iZone,sColor4,rDUMMY);
Note that for JPEG images (and other "picture" formats) the iZone and sColour arguments are not used (I suggest you use 0 and "" respectively). Where the images overlap, the colours are blended.

Subject: [gxnet]: Grouping Images
Is there a way to group images?
What I have are a bunch of JPEG images that I would like to place on a map (via a modified version of GRIDIMG) such that they are all part of a single group that could be hidden or not as desired. I can use the modified GRIDIMG to specify where I want an image to go easily enough but I cannot tell whether or how I might append an image to an existing group (i.e. image(s) ).
Is the answer that I have to do the layout in some other program (such as Adobe Illustrator) and then import the composite image?
