I can't upload files to garrysmod.org

Please forgive this post, noone answered it in the other forum and I feel that may have been the wrong section to ask, so I’m posting here.

When I try to upload my adv dupe file to the site, it comes up with “The file contains useless files. DO not upload just text files or just image files” yet the .zip file contains both a text file and an image.

Will someone please help me with thos problem? I would be greatful for that. Thanks.

Why did you upload just a text file and an image?
“The file contains useless files. DO not upload just text files AND or just image files”

Erm, it wasnt just that - the zip file contains an advanced dupe which IS a text file* along with the screen shot - it was a ZIP FILE that contained these 2 things. What am I supposed to put in there besides that for the website to accept it?

Should I create a junk.lua file or something?

Maybe a readme should help?

That’s still a text file.

I put a file in it that is titled “donotreadme.lua”

I didnt know what else to put in, so now it’s uploaded
