That colored swirl image you have modified to incorporate the Steemit logo in the center is not correctly attributed to you. It's actually a painting called Black Hole by Fabian Oefner. You could argue fair use, but in my opinion you are violating copyright ownership of a great yet relatively unknown artist here.
I actually recognized it because I'm a fan of the band Dawn of Midi, who have permission to use it in black and white on the cover art for their debut album.
@personz, I very much appreciate your alertness - it was an image I played with when putting graphics ideas together for steemnews.online - I shall change the attribution straight away and I thank you again. I am not a plagiarist, I assure you!! Namaste. Upped and followed.
That's good but it's not enough. I'm going to leave it at this but you can take it as given that unless you have explicit permission to use an image, in the form of a license or written permission, you are not permitted to use it. Attribution is enough only as permitted by license. There is no such license for this unless I'm mistaken.
Again fair call, I shall just remove it. I apologise, I was in the midst of a very full-on discussion and wanted to tidy things up. Give it a minute and it will be gone!
Much appreciated.
