    I'm talking about specifically the program "Logo Creator"

    Anyway I've seen it happen before with other programs I use and I don't know why.

    Basically the problem is this:

    I make an image and it has a white background. Perfect. It looks white. I save it. I upload it. I look at it online and perfect, it's white.

    Now, after looking at it w/ my pentium3 pc hackintosh, and an old pc (celeron 1000), one day I'm looking at the image w/ my laptop (acer pentium3-pc) and the image has a grey-ish background!

    The backgrounds basically white but you can see the borders and the background is greyish.

    So I load it up w/ a friends 4-year-old pentium3-ish 1.7 or 2.3 and the damn thing is like completely grey background!

    These computers all have Windows XP, except the main one I use has the cracked mac osx.

    I just don't get it. I don't know if its the computers cause on an old celeron 1000 the images looked fine. And I don't think it's the monitors cause the pentium except the laptop the monitors are all thin-screen lcd acer monitors.

    lol anyway ... thanks for any help.

    Could part of the problem simply be different monitor brightness settings on the different computers?

    I don't know anything about Logo Creator but if the image that you're working on is in a format that Photoshop (or Photoshop Elements) can read -- .jpg, .gif, etc. -- I'd use one of those programs to clean up the background. For instance (these happen to be the instructions for Photoshop Elements 2.0):

    Copy the image to the clipboard.

    Paste the clipboard image into a new file in Photoshop.

    Select the "Magic Wand" tool and click on the part of the image that's supposed to be all-white. Adjust the selection if necessary, with the "Selection Brush" tool or whatever else works.

    With those pixels selected that you want to whiten, click on Enhance | Adjust Color | Hue/Saturation.

    With "Master" showing for the color, dial the "Saturation" slider all the way to the left (-100) and the "Lightness" all the way to the right (+100). That should give you pure white in the selected area. You can verify that (after you close the "Hue/Saturation" window) by selecting the eyedropper tool, clicking on the white area, then clicking on the white "Set Foreground Color" square and reading the numbers for that color. If they say "255" all the way down, you have white.

    Save the result to an appropriately-named file.

    use photoshop to delete the background and save it as a png and you wont have a background colour atall, this way you wont see the box around the picture on different computers. also what browsers/versions are you using? this could be contrbuting to the problem.

    Stealing is illegal, even if it's online.

    Stealing on the internet is not different than stealing something from a store/building in real life. It's your choice if your going to do anything about it, but remember what you're doing is wrong.

    re: gray background

    What format are you saving the images in? If it is JPG, then that does not surprise me at all. JPG, in its compressing process, will modify colors a bit to get the best compression. You don't notice those subtle color alterations on photos, but when it comes to saving images with some expanses of solid colors, you will see some changes.

    You might want to save your images in PNG, GIF or even BMP formats.
