If I take a theme and customize it, using the basic layout but changing header, colors etc. do I still need to leave the link to the original creator at the bottom? I don’t mind giving credit where due, but hate to say “designed by” someone else about something that is going to have my original artwork on it.
How do I find out? There is no Read me file in the folder. It’s one of the themes in the WordPress theme directory. I went to the site of the submitter, but can’t find any info on license there either.
At the very least, the “Based on…” idea is always a good one, considering the fact that even if you feel like you’ve changed the entire look, you’ve likely kept good chunks of code that someone else may have taken awhile to work out.
In the case of the original question, I’d probably use “Based on…” in the footer, especially if one exists currently.
I actually hacked away at my theme and combined two themes into one. After I was done, my theme doesn’t look anything like it did in the beginning. So what I have done is in the footer, placed a string of text which tells users which themes my theme was based on and the theme names are links to the author’s respective web sites.
