Corrupted Image Files

Four days ago, I made the switch from blogger to wordpress. In my media library the images are not showing up.

All of the image names are long with “%” symbols in them. I spoke with a blue host representative, who said I would have to re-load ALL of the images and insert them into the posts again.

The night before a different representative from BlueHost told me that I could just rename them in the CPanel (but that is not working) the image namges have changed but the image is still not showing up. I have no clue what to do now.

I do not have all of the images, and that would take me forever!! Is there a way to fix this?

Thanks!
