I, personally, have no problem with them.
But some people on my board complain that animated avatars and images in signature get on their nerves. So why not make it nicer for them?

Besides, my hack is muuuuuuuuuch smaller (only 6 lines of code, unlike the one you gave link to), which makes it quicker.

To block animated gifs is a bit different than to block all gifs. Ok if you like we can discuss which file format has the best compression and is more suitable. The simple fact is gifs are everywhere so alot of users will have a gif they want to use. Your hack still has its uses and I'm not saying which is better or anything. However, if the thread makers had searched the forum maybe you wouldn't have spent the time making a png/jpg only avatar hack.

Well, just because you like them doesn't mean everyone does.

they're very anoying, especially the flashing, fast moving ones.

ps: I always use the search, but this time search results didn't show that hack for me.

JPG is better for pictures anyway

gif is more like for buttons, logos etc
And I have search the forum first, but didn't find the right hack, this ones serves me well.

yep your hack is just smaller and more usefull to me thanks again bro

I do not understand, how does THAT hack block only animated gifs... I see some xBLAHBLAH code, is that a frame break symbol or something? Besides, opening and reading a file will still be slower than just restricting the extension.

Dark Visor: I suggest you read the specifications of GIF89a, like the author of the hack in question has. It is however a correct observation that 0x2C is the image seperator byte in the GIF-stream.

That said. The hack is flawed because it checks the whole file, and not only the datablock that contains the raw imagedata. The image palette may also contain that byte in some cases, which creates a false positive.

However, a new hack which will be 100% foolproof is in the works.

I do NOT recommend that anyone installs a hack that completely block the GIF-format. The GIF-format deliveres the best compression for standard sized 64x64 avatars. JPEG usually needs more space to define the headers and palettes alone than a complete GIF file requires to deliver the whole image.

nso, where can I read the specifications?

Thanks dude. When you finish your hack, please PM me. Thanx.
