[gdal-dev] gdal_translate gif->gtiff warning

[Dori]

Hi,
I am trying to convert this GIF
https://picasaweb.google.com/izzybitsie/GDALImage?feat=directlink<http://aviationweather.gov/data/products/swl/ll_12_0_cl_new.gif>to
gtiff.
I used this command after assuming projection was lcc:
*gdal_translate -of GTiff -a_srs '+proj=lcc +lon_0=-95 +lat_0=25 lat_1=25'
-a_ullr $ulx $uly $lrx $lry ../maps/my_image.gif ../maps/my_image.tif *

If I try to view the image using ImageMagick I can see it but I get a
warning about TiffReadDirectory field tag 42112 encountered.  If I try to
view the same image with a proprietary software then, I get the same warning
but I am not able to see the image.
I used GDAL 1.6.0dev, FWTools 2.0.6, released 2008/02/03.

The info for  my_image.tif:

Input file size is 864, 526
0...10...20...30...40...50...60...70...80...90...100 - done.

.......
and the color table keeps going here

I cannot upload this image to Picasa, but if needed I'll look for a file
server.


Q1: is there any easy way to find out if this warning is caused because I am
using the wrong projection?
Q2: Does the command I am using look OK?
Q3: How do I get rid of the warning to try viewing the image with the
proprietary software?

Thanks
