"Peter creates the Advanced Suit (Earth-1048) on Marvel's Spider-Man.jpg" is not a valid filename. It should be "Peter Parker (Earth-1048) from Marvel's Spider-Man (video game) XXX.jpg" with "XXX" being a sequential number that corresponds to the number of images uploaded of the same type.
Similarly, "Hammerhead vs Spider-Man and Silver Sable on Marvel's Spider-Man (video game) (Earth-1048).jpg" should be "Joseph Martello (Earth-1048) vs. Peter Parker (Earth-1048) and Silver Sablinova (Earth-1048) from Marvel's Spider-Man (video game) 001.jpg"
"Hammerhead enhanced by the Project Olympus on Marvel's Spider-Man (Earth-1048).jpg" should be "Joseph Martello (Earth-1048) from Marvel's Spider-Man (video game) 002.jpg"
Please, whenever you create a new page, don't pass over writing some history text.
It's important to take into account that the purpose of this wiki is to provide the information of any given Marvel subject to visitors who want to know about it. Having pages with barely any information at all is counterproductive of us and discouraging for the readers, who would click on the link for a page only to find a "History of character is unknown" when the article has much more potential than that.
2) Once the image is uploaded, please don't forget licensing.
If you uploaded it through the Special:Upload function, make use of the "Licensing (Required)" dropdown feature before clicking "Upload File," and choose the apropriate type of licensing. "A single panel of a character," "A regular comic book cover" and "Movie screenshot" are some of the most common options.
If you uploaded it through the "Add a photo to this gallery" function on the bottom of galleries, or you didn't select any licensing option in the dropdown feature of Special:Upload, you'll have to add the licensing manually. Go to the uploaded image and click "Edit," you'll see two rows of buttons to insert templates or format functions. Click on the button that has a single polaroid photograph on it (found in the bottom row), and the template will be added. Be sure to fill in the "License" field with the respective license. Most common licenses are "Comic Single Panel," "Comic Cover," "TV Screenshot" and "Movie Screenshot." If the licensing you added is not valid, the image will still appear as unlicensed.
3) Whether the image template with licensing has been added automatically or has been inserted manually on the image, please be sure to fill in the respective fields there are, including "Source," "Universe," "Subject#," etc. to help sort it out.
It doesn't matter who takes them, they still need to be named in accordance with the Marvel Database:Naming Conventions to be uploaded here, as well as properly licensed in order to be legally displayed on the wiki.
A few members of the admin team included myself noticed your edits and undid them, since we couldn't find any confirmation that Earth-90718 is in fact the reality designation for the reality where the PS4 Spider-Man game takes place. Could you please tell me where did you get this designation?
I saw it on another wiki, and i thought to put it here too, anyway, sorry if i did anything wrong, i just wanted to contribute to the fandon. Mind telling me how the realities are numbered? someone said to me that fans normally do it
You don't need to worry, you're not in trouble. As a matter of fact, fans are not responsible for the assignation of numeric designations. All numeric designations used in the Marvel Database need to come from official sources, like a comic, an Official Handbook of the Marvel Universe update, or through the Handbook's irregularly-updated online appendix (here).
But you're not entirely wrong about fans giving realities numbers. When a reality hasn't been given an official designation, we make use of the Temporary Reality Numbers system (you can click on the link to learn more about it). However, we always clarify that these numbers are not official, and we don't encourage their use outside the Marvel Database, since TRNs only serve an utility purpose within this site.
Do you mind also telling me in which wiki you saw it?
