Hi, sorry, I may not have explained it very well, but it seems you have answered it.
Yes I want to watermark images that are not uploaded using the wordpress media library, example the forum I use, if users upload images, they will be uploaded to the forums ( forum/files/) folder.
I dont want to manually watermark images, I would want a plugin to do it automatically, as this would, but using a different directory.
Im not too familiar with php, but with a little guidance can usually get round problems.
I would be grateful if you have any ideas/code I can use to make this work?
