the bit depth number seems off, since CS only works with 8 or 16 bit images. maybe it's referring to a different value. anyway, it shouldn't change things:
ok, here's what you should try:
open up one image in pshop. on the right side, you should have an actions palette. click on the new action icon or the delta in the top right and select new action. name it resize or whatever you want and make sure it is contained within the default set. then go about resizing this image the same way you would any other. at the end click save as and save it as a new image just like you would normally. once it is saved, click on the stop recording button. your action will now be saved.
now, open up the photoshop browser (file > browse).
find the folder that has all the images you want to resize and open the folder.
select all the images.
click automate > batch
the batch window will open, choose the action you created from the drop down list (make sure default set is chosen).
make sure the "override action 'save as' command" is selected (this allows you to choose the folder they are saved in)
select a folder for the images to be saved in and click ok.
this is how I do it in CS, i think you should be able to do this in ver 7.
