[SGVLUG] Graphics

[listreg]

Yes, it should be visible but just so you can tell what it is. I don't know Gimp. I'm not into graphics.

>Do you want this "watermark" to be visible to the end users, or useful as proof that your image may have been copied far and wide without your knowledge or consent [of course, putting it up as a background pretty much consents to copying far and wide in the first place, but it sounds like you have other reasons for being concerned]

>If you want the watermark to be "visible", and possibly semi-annoying [along the lines of the "bug" that you see on televised movies], you might consider a simple greyscale image that you apply as the "alpha" channel of the image in gimp - this will "slightly fade" the image where it is "grey" and leave it untouched where "white" [or maybe the other way around -- play with it till you get something you like]
