It's coloured grey too. I've opened the gif up in photoshop, but cannot work out how this gif has been made, where you can see the background logo through the greyed table cells - the grey is the gif).
I tried making one from scratch in photoshop, but didn't even come close. All I know how to do is make a completely transparent gif with no colouring.
Does anyone know how to make one of these?
Any help would be greatly appreciated it,
the boy duck

Sometimes old versions of Netscape render transparent gif areas black. So - let's say you have a checkered tile with diagonal boxes rendered as transparent - those areas may show up sketchy black over a solid colored background. Lots of times hitting refresh fixes that in old NS, though. (Not that every viewer is going to know that.)
Also, if the uppermost top left corner isn't transparent, sometimes that makes a difference in old NS. (Switch non-transparent area to top left, if possible!)
Lastly, when you are saving your image, be sure your background .gifs are not both transparent and interlaced, or they may cause rendering problems. Sometimes you may forget that you have "interlaced" chosen by default on your graphics program, so you may need to double-check your settings before saving the background image you wish to use.
just some weird stuff maybe your mother never told you about :)
I know of a problem that can cause something similar, and it's to do with the way many graphics editors implement transparency in GIFs: basically, it's an animation, and the "transparent" bits are in fact set to "revert to previous state" after a split-second interval (a few hundredths of a second). Sometimes the interval seems to be set to a value that causes one or two browser builds to choke, and you have to mess around a bit with the headers. However... it's never caused problems for me as far as I know.
Transparent = colorless
Transparent is without color, ergo, the background color shows through.
Easiest trick: grab that gif, save it to file, open it in a graphics editor like paint shop pro, and enlarge or resize the canvas to whatever dimensions you need. Save it as a gif again, go into some compression software, compress it down to one color, whallah!
There's this tiny transparent gif at a site.
It's coloured grey too.
I think the effect being described is actually what you would call "translucent," in which case the grey/transparent checkerboard technique described above is probably as close as you could get until full browser support of alpha transparency via .png becomes a reality.
(Now there's a run-on sentence only a graphics geek could love... hehe)
One thing about the tints is that if you've got paragraphs of text on a tinted background - it can make the text appear sort of dirty - I don't know why. This is making me think background tints are better suited for single lines of bold/big text.
[Thanks for all the tips btw]
Is this basically the same as planting a series of pictures onto a transparent base in Photoshop, saving them, and sticking them into a GIF program?
Or is it some option that I haven't unlocked in the GIF animation programme...?
Just had a look at Gif Construction Set's site and they do offer transparency creation.
