Yesterday I wanted to change my Signature on this forum, but I wasn't able to change it to a picture from my computer. What do I have to do to make it working.
It looks to me like you did because there is a broken link to the image underneath your comment. I would check the link to the image you want to use is working
Sorry what I meant is you can't upload images onto this forum, we don't have the server capacity for you to be able to do that. You will need to host your image somewhere else on the internet and then link to it here.
Yes! As you see, I have found something for everybody who also want to upload an image: http://www.pic-upload.de/
