I have around 50 Portfolio snaps with 1200 by 1800 size and Pixel as 300 . Before I send it to anyone I want to make it in such a way that if anyone tries to enlarge it, image shld get Blurred. How and what to do ? I dont have Photo shop. Reducing Pixel to 72 will help ? I tried Irfanview but No help.
If it isn't a vector, it will get blurry if you enlarge it.. You could just resize it to half its size (or even more). And/or you can add a watermark (your name or something) Tutorial how to resize image with irfanview http://www.bleepingcomputer.com/forums/topic65221.html Code (markup): Tutorial to watermark an image with GIMP http://www.scottphotographics.com/how-to-make-a-simple-watermark-in-gimp/ Code (markup): BTW: GIMP is free
