Use of freecodecamp images in Course projects

Probably a stupid questions but I have used images from other freeCodeCamp projects as a placeholder for my certification projects - especially the portfolio one as a placeholder, Code was written from scractch but nothing was attributed for those images - hope that is acceptable as part of certification?

Sure. I wouldn’t worry too much about the cert projects. Now, when you get to actual sites, like if you do a “real” portfolio site, etc - then I might pay a little more attention.
