I see you're not creating pages correctly, NewYorkCity101 also informed you about this but you're continuing, here's an easier guide.
Visual editor changing to source editor
You're most likely creating pages with the visual editor, if not, then good job. If so, here's the tips.
You're firstly going to see an easy-to-use interface. However, using this editor can break the format of pages and you also can't centerize images with it. Now, for the tips.
Click on the Menu icon, next to the Edit notices button.
Press Source Editor.
You've switched to source editor!
Now for the main part.
You're gonna see a button that looks like this:
Press it. It's going to create a header that looks like this:
That's going to make a lowercase "P", as you're making headers with "????-Present" and not "????-present"
Change the year
Insert a photo
Centerize it by writing "|center" and remove "|thumb"
Add "|200px", "|250px" or "|150px". These are the sizes of your image and you need to add a size or else the page will have the biggest logo on earth.
Here's the code for the correct version.
==Former name (optional)==
[[File:BackRub logo 1996.svg|center|200px]]
Hello, I have to be honest, you constantly posting forums is particularly annoying. In fact, we find forums in general particularly annoying. If you need something on Logopedia, I would rather you would just message me or any other administrator (Logopedia:Administrators). This way we can get back to you faster, thank you.
You should NEVER insert an image as a thumbnail and you do not have to say in the image that it is a logo for a certain company, that should be obvious. You should give an appropriate size for the image, 200px or 250px is standard. Please fix your mistakes and remember this for the future, you will be blocked if you continue to make poor edits. Thank you.
