Xara Designer Pro X: I've built a WEBsite, and it works fine. However, I've done a great deal of work with individual graphics in very high res at 96 DPI. It is my understanding that if I reduce the DPI to 72 that if some one copies the file and brings it up in a program it will be a great deal smaller than my inserted graphic, and if it is enlarged it will fall apart. I need some confirmation on that please.

Also, all my files are .JPGs. How can I make the DPI change without losing the original quality? Any help greatly appreciated. I'm Watermarking the graphics, but any decent artists can undo that. Thank you.
