There’s a running debate over in the creative office here today. The Research and Development team are questioning the Design team on the configuration of images for websites.
The question is: Should a designer spend time dividing the image into sections so that the webpage is loading up a number of separate files, giving the appearance of a faster page, or should the image remain one file?
The argument against division is that it is not actually faster, it just appears to be and on top of this, you have to write more code for each complete image, which may affect the speed.
I got out of the argument when it got down to “it depends how clean the code you are writing is.”
I know plenty of businesses that do it one way and plenty that do it the other. So does it come down to personal preference, or is one way really better than the other?
