So how do I measure that?
Hi, I've prepared a web page with two images. One is ONE dpi and the other is set to ONE THOUSAND dpi. Both images are 100x100 pixels. They will appear identical next to each other in the web browser. They will also be the exact same file size and they will take the same amount of time to load. Here it is: http://www.obscurasite.com/jon/images/dpi/demo.html Note: Both files were saved with the exact same amount of JPEG compression. If I wanted to make them load faster I could have boosted the compression to get a smaller file size but the quality would have suffered. (gimp shows you the damage as you adjust the amount of compression... find the sweet spot and you're golden) Now go tell all your friends... In the crazy world of html dpi doesn't matter! :-) -- Jon Winters O O O O O O O "History Will Prove us right" <O> <B> <S> <C> <U> <R> <A> http://www.obscurasite.com/jon/ / \ / \ / \ / \ / \ / \ / \ _______________________________________________ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
