I've expirienced some problems with exporting images and graphics to
gif and animated gif's with Export[]. Here are inputs for exporting
lists of graphics as well as images

In[138]:= Export["E:\\work\\projects\\anim2.gif",
 Table[Graphics@
   Raster@Table[
     k - (i + j), {j, 0, 0.5, 0.05}, {i, 0., 0.5, 0.05}], {k, 0, 1,
   0.1}], "GIF"]

Out[138]= "E:\\work\\projects\\anim2.gif"

==========================

In[148]:= Export["E:\\work\\projects\\anim4.gif",
 Table[Image@
   Table[k - (i + j), {j, 0, 0.5, 0.05}, {i, 0., 0.5, 0.05}], {k, 0,
   1, 0.1}], "GIF"]

Out[148]= "E:\\work\\projects\\anim4.gif"

The arguments of exports are evaluated and shown properly, but
resulting output files are corrupted and unreasoonably small (390
bytes)

On the other hand selecting an image in frontend and choosing "Save
Image As..." to save as gif works just fine. However, I need to make
animated gifs and this trick doesn't help.


Is it a bug in GIF converter or what?
Any advice would be appreciated.
