Hi all, I ended up using StringJoin and ToString for the dynamic file names, and ImageAssemble to import building block images for the final merged image. I created the "building block" images with Fireworks. I also padded the composite image on the top and bottom if the width x length proportion of the jpg was wider than 660 x 440. m=1;n=0 0 n=n+1 1 * * * If[Length[IntegerDigits[m]]+Length[IntegerDigits[n]]+Length [IntegerDigits[m n]]==5,Export[StringJoin["03","-",ToString [m],"-",ToString[n],"-",ToString[m n],".jpg"],ImagePad[ImageAssemble [{Import["pad.jpg"],Import[StringJoin[ToString[m],".jpg"]],Import ["times.jpg"],Import[StringJoin[ToString[n],".jpg"]],Import ["equal.jpg"],Import[StringJoin[ToString[m n],".jpg"]],Import ["pad.jpg"]}],{{0,0},{50,50}},CMYKColor[0,1,1,.2]]]] * * * Diana On Aug 12, 1:32 am, Diana <diana.me... at gmail.com> wrote: > David, > > Thank you for explaining how to do the export with ExpressionCell. > > I have a two part followup: > > 1) I want to do hundreds of these files, and would like to use a table > and variables which change.
