I didn’t know that! You’ve explained it so very clearly (or, as they say here in the South, you’ve really “put it down where the hogs can get it”) which is very helpful. Thank you, Yep!

Actually, ‘compression’ and ‘resolution’ are two different things. Compression refers to the way the file is stored on disk. Resolution is the pixel dimensions of an image (for instance, the banner above has a ‘resolution’ of 806px x 190px). Two image files can have the same resolution but have different levels of compression. The standard JPEG file format has many levels of compression and is considered ‘lossy’ compression, which means that the image degrades in quality the more it is compressed.

“—save file at a higher compression — or at a lower resolution, which means the same thing.”

They mean the same thing? I thought one had to do with the way the computer deals with photos and one had to do with the way the computer deals with the binary of the file.

I really don’t dive too deeply into photos because I have no artistic talent but it would seem to me that if you were one who cared a lot about the quality of photos you put on the web, it might make a big difference which way you went.

A photographer or technophile could very well have a different answer than I, but in the end both “compressing” and “reducing resolution” produce smaller, faster-loading photo files, which is all that matters to me!

Thank you, as usual. When I have time, I’m going back to your earlier instructions and learn to wrap photos and text. Post some more blog tutorials. We all need them.
