777246 2009-05-27 02:56:00 Can anyone tell me whether the file size of an image used as a desktop backround has any effect on performance? Tony (4941)
777247 2009-05-27 03:23:00 Yes it does Rob99 (151)
777248 2009-05-27 03:47:00 Yes it doesI thought it would - is it obvious, or fairly subtle? I'm creating some training material for Seniornet - and all these people like to have pictures of grandkids on their dektop, so it would be good to be able to give them a bit of a steer. Tony (4941)

777250 2009-05-27 03:59:00 IIRC iconss thumbnails are loaded in a cache, so it should affect the performance I guess Blam (54)

777252 2009-05-27 04:41:00 If you want to use a certain picture, depending on the OS, safe it as a JPEG.

The quality is usually good, you may get better if its saved as a BMP, but the difference is not that noticeable, yet the size will be - A LOT has to do with the quality of the original Picture to start with.

777253 2009-05-27 05:07:00 Perhaps the wrong question was asked.

Maybe it should be is there a difference in performance when using a 3.5 megabyte JPG as opposed to a 256 Kilobyte JPG for a desktop background?

I could be wrong though.

I've realized though, that "performance" could be misinterpreted. I meant "will it slow down the machine", not "will the file size make a difference to the quality of the image" - which is what I think a couple of posters may have thought.

Ok, it'll affect performance, but you shouldn't notice it. Unless you have a REALLY slow machine.

Having a clear background behind icon text and aero etc does use a bit of memory however.

Have a look at dwm.exe(If you're using vista) in task manager
