I'm not very familiar with PostScript, but you might be overflowing
the maximum allowed string size.  Instead of putting the image data
directly in a string, try using a procedure to read the image string.

10 10 translate
150 150 scale
/myimagedata 450 string def
150 150 8 [150 0 0 -150 0 150] 
{ currentfile myimagedata readhexstring pop } false 3 colorimage
IMAGE DATA
showpage

450 is the size of one line of image data (3 components * 150 pixels).
IMAGE DATA is the same data you were already producing, but in a
slightly different place and without angle brackets < >.
