I run a blog on blogspot, and I want to add pictures into this blog. However, I want them all to have the same width (whether they are portrait or landscape) to keep my blog looking uniform. The space I have, means my images can only be roughly 15cm wide (width), and in order to post them as 'original size' I need to adjust the size in photoshop. However, this obviously loses a lot of the images quality, making it look very poor because of the lack of pixels! I know this is possible, because so many other bloggers have done it!
I save it for the web, as a PNG24, and the highest quality there is! (10)
Any suggestions would be HIGHLY appreciated! Thank you in advance!
