Jpeg or Bitmap

Monday, February 7, 2005 by teddybearcholla | Discussion: WinCustomize Talk

I have never thought much about this until recently. I have always uploaded my wallpapers in jpeg for preview and bitmap (zipped) for download, as stated in the form page for uploading. Bitmaps at least mine, are large in size even when zipped. I have noticed that a lot of authors zip jpegs, which are a lot smaller in size. Does it make any difference which way to go, zipped bitmap or jpeg for downloading ? If it doesn't make a difference, then I will do jpeg, because as a dial-up person, they download a lot faster

I think most people zip jpgs because of the smaller file size and it is perfectly acceptable.

You can do it either way, but as pictoratus said, if your trying to save space, jpeg is smaller.

But Bitmaps look better

You are right, SD, they do look better. But for the desktop, I'm not sure that there is that big a difference in how they look, I could be wrong...actually been wrong lots of times! Isn't png better than jpeg? If it is, couldn't that be a compromise between jpeg and bitmap?

But does windows allow you to use a png file as a wallpaper?

I just found this -> http://office.microsoft.com/en-us/assistance/HA010548631033.aspx

This lists the type of graphics and what they are about.

Weaksid, that is an excellent link, definitely in my favorites! As for windows allowing png use for wallpapers, I don't really know. I have my wallpaper folder which is huge, in my cdrive and I just browse insead of the regular way to retrieve the wallpaper I want,and there are some in png format. When I am creating wallpapers, I save them in png and I can set them as desktop wallpaper without any problem.

Yea, I just checked the browse and it has png in there. I didn't even think about looking. I just got up a little bit ago

Jpegs are smaller in size and good at quality but they are more vulnerable to virus attacks then bitmaps. Does any one remember win95.funlove ????

I had lost all most all of my wallpaper collection due to tha virus

Not to get too technical (because I can't ) but, Bitmaps and .bmps are not the same thing. A Bitmap is a catagory of digital images in which .bmps, .jpg, pngs, etc, all fall under. Just wanted to clear that up, its been bugging me. Oh and something vertically level is plumb not level.

Glad you said that NT. I always wonder if I should point out things like that, and run the risk of sounding like a nit-picker, but it's important that we're all on the same page.

ok, so I am on the same page, with what you said Night Train and what Kosati was thinking, is that on the upload page, it doesn't actually mean you have to use a zipped bmp, it can be a jpeg if you want!

I knew about the bitmap thing, I just didn't notice that's what they said. To take the info one step further, there is Bitmap and Vector, By what I know there is only two types so it's either of them.

TBC- zipped .jpeg's are best for transfering files. They are much smaller than .bmps. For uploading purposes I strongly suggest .jpg's. It's faster for everyone and easier on the servers. Quality of the image isn't a factor I think.

I was just being a picky in my earlier comment. I didn't mean to confuse at all.

In some windows based network environments, .bmp images will be displayed whether the computer is locked or not.

If you use a .jpeg for your wall in these environments, the .jpg will display while you are using the computer, but when locked; the background color will be displayed.

I have seen this in both Windows 2000, and Windows XP networks with a lot of user profiles set-up.

I am not sure why, other than .bmp being native to windows, and perhaps an issue or bug with active desktop.

Probably not important to most users, but just in case.
