why isn't Google Images formatting my photo links properly?

Google Images won't display thumbs fr my site nor proper links

My blog used to be hosted at Typepad. When it was, Google Images seemed to have no problem crawling my jpgs, displaying them on their site & bringing visitors to my site to see them.

Now I've moved to WordPress & Google Images is making a mess of everything related to my images. I know that GI is crawling the images because I'm getting hits fr. folks who find my images there. But when I check out the GI URLs for my images (which the visitors used) I see that:

a) GI doesn't display a thumb or the lower-screen preview of the pg. where the photo is located
b) GI displays a truncated URL link for the pg. at my site where the image is located (like this "www.ri")
c) If I click the 'See Image Alone' link, I'm usually taken to my site main pg. rather than the image file

A few notes about my site:

I've activated Hot Links Mgr. through cPanelx (too many people direct-linking to my images & music files). But I DO have the GI domain listed as an allowed site. Is there a possibility that my server is denying Google Images access to my site even though their domain is listed as allowed? If so, is there a way to correct this? Also, I've noticed that many of my images do NOT have underscores in their file names (i.e. "http://www.myname.com/blogname/images/this is a file.jpg"). Could this be part of my problem?

If so, I had no idea that this could screw up Google Images. Do I have to go through all my images & add underscores to get GI working properly? Or does this not have any bearing on my problem?
