Deleting unwanted image textures

I have a texture mess. I was using massive files (downloaded from Mayang’s free textures) as image textures for my BGE project, but it made it crash. So I cropped all the images down to 64x64. Now, I can’t seem to update all the textures. I had packed it, but now I unpacked it, and I it still won’t reload. I have about 10 images textures, and each one could choose 10 images. It seems like I have to go through each image on each texture to fix the problem. Can I just delete all of them and start over?

Thanks,
Vendetta

yes, tex have to be small for your video card. You can delete (deassign) the textures so they are not used, save, and the re-open. Blender does not re-open or re-create any unused materials or textures, for this very reason.
