Picture indexing question

I have made a little blog and made around 5 posts. It is just a simply blog nothing special. However only 2 out of the 6 posts have had their pictures indexed into google images.
I made another blog at the same time as well and have had all those images all indexed. It's been over 3 weeks since i made the posts. but the blog has been online for longer.
The actually post is showing up in the normal google text search but the images aren't.
How can i fix this?
