Textures not rendering

Hello BlenderArtists,

Ive been working on a little scene to try and work on my texturing skills. It had all been working until I rendered and image to make as my desktop background, and went back to render it again after some changes, and the textures were not there. I opened up a previous version of the same file ( As I progress, I do “Save As” and change the file name in case I make a mistake ) and the textures were not rendered. I am confused as to why that particular save doesnt render the textures. Are they’re any hotkeys or something I might have accidentilly pressed to cause this?

Thank you for any information you might have for my issue.
