I'm sure this fandom is fed up with watermarks, so here is a tutorial on how to remove a watermark from a photo. I don't recommend this for anyone who isn't patient, it's not so much skill that you need, just a lot of time.
Please do not use this method to remove someone's watermark from an edited photo. Please give all photo rights to any photographers you may be removing the watermark from. I do not recommend you use method this to just post the picture, but rather to edit it or use as an icon.
Open your image in Photoshop.
Use the clone tool by holding down option, then clicking the spot you want to clone.
Use the brush of the clone tool to paint over the watermark. Caution: You will need to continually need to change the original cloning spot to be accurate.
If it looks repetitive or sloppy you can use the healing brush tool and the blur tool.
Color and sharpen as needed and save!
This can also be done with any other editing program with a cloning tool such as Pixlr.
If you have any questions, please don't hesitate to ask.
