Hi Thanks for the follow up.
Here I am talking about the original IJ1 updated to the latest build 1.49c14.
I also have installed Fiji in the same computer, but I get the wrong LUT with
IJ1 (and not the Fiji install).

There is no such command in IJ1.
I can confirm that the cached blobs.gif loads from the net (when there is no
cache) correctly as inverted LUT:
Title: blobs.gif
Width: 256 pixels
Height: 254 pixels
Pixel size: 1x1 pixel
ID: -16
Coordinate origin: 0,0
Bits per pixel: 8 (inverting grayscale LUT)
Display range: 0-255
No Threshold
Uncalibrated
URL:
http://imagej.nih.gov/ij/images/blobs.gifScreen location: 10,148 (1920x1200)
No Overlay
No Selection
but from the cache it shows grays LUT:
Title: blobs.gif
Width: 256 pixels
Height: 254 pixels
Pixel size: 1x1 pixel
ID: -12
Coordinate origin: 0,0
Bits per pixel: 8 (grayscale LUT)
Display range: 0-255
No Threshold
Uncalibrated
URL:
http://imagej.nih.gov/ij/images/blobs.gifScreen location: 10,148 (1920x1200)
No Overlay
No Selection
I cannot imagine this being desirable. Inverted LUTs are confusing enough, to
then have the software decide how to load the data.
Cheers
