Lets say the blog you are writing for wants images to be 600px wide. You create a screenshot that is 800px wide. You can either resize/re-scale it in Photoshop or a similar app to make it 600px wide. Or upload it to WordPress, and then change the display settings to display it at 600px (with the image still being 800px wide really). The former can result in distortion of the image, especially if it contains text. While the latter products better results as the image doesn't get as blurry. However, is it frowned upon to 'resize' images by changing their display settings in the web page/blog post? I know it used to be as people used to upload massive photos that were 2000x1000 and then just use HTML like img src="image.jpg" width="600" - but now is it such a big deal? Especially when were not working with photos, but a PNG that is only 200px smaller? Thoughts?
