blogger Image problem

I can't figure out why blogger isn't allowing a viewer to click on an image and for it to appear larger in a new window. I think the problem is that once I place the images into a post, I later cut and paste them to where I want them to appear within the post. I think this is causing me to lose the link to the original image saved on my computer. It's driving my crazy because I'm not copying and pasting, but linking the image using the upload image tool. Anyways, i'm gonna repost all of my image uploads from my post about handwritten type and see if that will work any different. Let's see if this works!
