Background Images

I found a modeling sheet for Dib from Invader Zim. I cropped it so i wold have separate files for front, side, and back. When I set these up in blender for my references only the front will show up. I set it up as 3 different instances of using images, one for each view. When I switch to side or back no image is displayed. I’d appreciate any suggestions

Did you set the correct view in the Background image panel?
Are you in orthographic view mode ? (toggle between orthographic and perspective with numpad5)
Did you set it up for Right view but are actually looking at Left view ?
Attach blend file (pack your background texture in the blend from File menu)

i had the wrong side selected. thanks
