eps file does not open after resize

[wizard]

any help would be appreciated

i want to create thumbnails of eps files using nconvert. at first it was not possible but after downloading AFPL Ghostscript it goes ok. BUT...
after thumbnail generation when i try to open the created thumbnail with photoshop the first thing i see is a window titled "Rasterize Generic eps format". well if i complete the procedure and save the file as eps from photoshop, then and only then, the file thumbnail is viewable from my custom made thumbnail-viewer. The original file opens from photoshop without any problem. is it something i do bad on conversion?

ghostscript 8.5.3
nconvert 4.57
line of code i use
nconvert -quiet -ratio -resize 150 150 -o rr.eps aluit-la.eps
thanx in advance
