I think perhaps one69chev meant https://fanart.tv/?
I did find a lot for great images to work with on that website, both for the art and logos.
I’ve also tried the gimp image editor. It’s a bit confusing but I think I could get the hang of it. With some practice.
I’m still gonna be looking for help with finding transparent white logos for 20th Century Fox, Lucas Film, and Blu-ray. In what format should I be looking for those? PNG? GIF?
And does anyone have pointers for properly sizing, centering, and cropping finished images to accommodate the hole on a full face optical disc?
Yeah, that is the one, sorry for the mix up. Gimp is not the most user friendly program, but they are a lot of tutorials on youtube, so maybe they can be of help.
As far as tbe other logos go, you can often find stuff like the in other fonts. “Episode 1” font for example has both Lucasfilm and Fox. The blu ray logo can be found in a font as well. Places like “Dafont” have a bunch of them for free. Download what you want, unpack, right click and hit install.
