    Hi...

    I like to play around with logos similar to the one that is attached here. I have been reading lately where some are saying that a PNG image is favorable to the older GIF format.

    I use a dial-up connection so I am not only concerned with quality and having more editing options with the image but file size as well.

    Now... the image here definitly looks better as a GIF than say, a JPEG. You can see that the JPEG just isn't as "vibrant".

    Which format, PNG or GIF is better for my needs. Again, quality and editing options and file size are important.

    Thanks in advance

    DAVID

    One concern should be browser compatibiliy... I believe gif is more compatibile across the web

    Yes like buck said because if you have a image that has no background and save it as a .png and you use IE that does not support .png then it will add a background to the image. So using a .gif is best.

    .gif is 256 colors
    .png is 24 bit high color so will look better.

    PNG is a better format that 99% of your visitors are going to be able to see. Keep in mind, though, that IE6 doesn't support PNG's alpha transparency (it can only render a single color as transparent, similar to a GIF). Microsoft, as usual, seems to think it's 1992. Luckily IE7 does support the PNG alpha channel, so when most people are using that version, it will finally be safe to take advantage of it.

    Thanks... Well the main thing I would use these logos for would be a web page. I tend to like black or at least darker backgrounds. Like the attached image... if I were to use that on a black background, would transparency even be an issue?

    The attached image, which is in GIF format was saved without any transparency so would that image look the same as a PNG.? In other words... would the attached image, provided it were on a black webpage, work as a PNG?

    Thanks

    David :)

    A .png without a background I think IE would add a white background.

    If you know what the background of the page will be... just start your new logo canvas with that color

    OK.. Now I'm a little confused. The attached image is just one image, without any multiple layers or anything. I'm not sure there is even a background there, if I'm not mistaken.

    Yes, PNG's without transparency work fine in almost all browsers. If you have a solid-colored background, there's no reason to use transparency.

    Thanks... Like Buck mentioned and Erick also shed some light on as long as the background color is the same as the page color then transparency isn't really an issue. I guess I was somehow confusing BACKGROUND and LAYER... which are obviously two totally different things. Yes.. the image then does have a black background.

    Thank You
