The wiki needs to be updated, namely like every section there is. Pretty much every one of the equipment stats / stats images are outdated. Also discard the ridiculous show level 10 stat of armor thing for armor.
How to help:
-> Log onto Spiral Knights
-> Goto Options and switch to windowed mode
-> Click on menu and bring up Recipes list
-> Mouseover the recipe until the window for equipment stats appears
-> Press print scrn button
-> Open up photoshop or paint or whatever, and get only the stat part of the picture
-> Save it as Equipment-Item_Name_Stats.png (forexample, swiftstrike buckler would be saved as Equipment-Swiftstrike_Buckler_Stats.png
-> Upload it onto the wiki, don't forget to add {{stats image}} into the summary box
here's an example for the swiftstrike buckler : http://wiki.spiralknights.com/File:Equipment-Swiftstrike_Buckler_Stats.png
Right now everything needs to be updated, add your stuff and then a list of whatever that's missing can be compiled later.

Yes, currently a number of the stats images are either missing or outdated. However, you need to name your files correctly. The format that is required by the template is Equipment-Item_Name_Stats.png (make sure you use uppercase for the first letter of each word. When uploading a new stats image (or you can do this for any that you upload, it doesn't hurt) put {{stats image}} in the Summary field.
You should also keep in mind that the game is in flux and many of the items are being rebalanced, so I wouldn't put a huge amount of time doing all of the stats images if it will frustrate you to possibly have them be outdated by a game update.
