Hello, I created a higher quality banner for the CHDK Wiki. Am I allowed to add it, and if so, how should I go about adding it? Also do let me know if this is the right board to put this in.
It's possible there's additional restrictions on the home page, but I believe if you are registered on the wiki you should be able to edit.
You should be able to replace the image by clicking on the image, then "more info" and then "upload a new version". That should replace all existing instances of the image, but in this case, it's only used on the home page (you can see usage in the "more info") screen. The previous version should stay available in the history.
You can also upload / add / replace images by editing the page, using the image icon in the toolbar at the top of the editor.
I agree your version is definitely an improvement.
Also, thanks for checking here on the forum, while edits are generally welcome, it's nice to have a post on the forum before changing high profile stuff like that.
