Not sure if that's a question for my mod, but I will answer anyway.
Certainly! Please provide me with the original text for me to paraphrase it.
Maybe I'm missing something. are you sure, this is meant to be in this thread (Rightful Ownership Multi Mod)?
Is it compulsory to upload sample images/cover art as stated in #7, or if we choose to, is it required to be uploaded directly?
For mods, the images can be omitted.
There's a template on how the opening post should look like in the mod and game uploading rules
Mod Uploading Rules
For game uploads, a cover must be present. For the sample images, I'm not sure.
Game Uploading Rules
See at the end of the first post, there's a "SPOILER: Template Preview"
If you use images, I would suggest uploading them to the post directly and add them by clicking of "Thumbnail" for a sample or "Full Image" for the cover art. Those two buttons appear next to the uploaded image.
See screenshot:
I'm not familar with the ruling on external file hosting for images, so I would just stick with the upload here on the page.
