I use this to merge png files - might be helpful. If memory is the
problem, at least you can combine as far as possible before resorting
to GIMP.

Greg

pro gm_merge_png,filenames,outfile,frame,vertical=vertical
;filenames - png files to be merged
;outfile - output filename
;frame - white border between images, in pixels
;vertical - set to merge vertically instead of default
horizontal

for i=0,n_elements(filenames)-1 do begin
im0=read_png(filenames[i])
if n_elements(frame) gt 0 then begin
sz=size(im0,/dim)
im1=make_array(3,sz[1]+frame*2,sz[2]+frame*2,/byte,value=255 b)
im1[*,frame:sz[1]+frame-1,frame:sz[2]+frame-1]=im0
im0=im1
endif
case i of
0:im=im0
else:im=keyword_set(vertical)?[[[im]],[[im0]]]:[[im],[im0]]
endcase
endfor
write_png,outfile,im
end
