Trouble uploading images throught exture

I am able to open some photos and some not as a texture. I go to texture, click image plane, then clock load image. For the images I need that do not open, I get a message “Unable to read specified file”.

I have tried to re-save file, move it around the computer, but some just do not work. They are jpegs, but other jpegs of the same size do work…just not all, and in particular, the ones I need. How can I fix this and what is going wrong?
Is there an easier way to load an image by chance?

Also, with the images I am able to load, I can not move or scale, how would I be able to do that?

Thanks, for whatever helps comes:/
