The Structure of a GIF89a file

This is a little technical but it will give users a real understanding of how the GIF works, and what you need to do with it. GIFs are composed of Blocks and Extensions. Blocks can be classified into three groups:

Control
Graphic-Rendering
Special Purpose

Control blocks, such as the Header, the Logical Screen Descriptor, the Graphic Control Extension and the Trailer, control how the graphic data is handled. Graphic-Rendering blocks such as the Image Descriptor and the Plain Text Extension contain data used to render a graphic . Special Purpose blocks such as the Comment Extension and the Application Extension are not used by GIF decoders at all. The Logical Screen Descriptor and the Global Color Table affect all the images in a single file. Each Control block will only affect a single Image block that immediately follows it.

Here's what a GIF looks like inside:
GIF89a File Structure

GIF89a HEADER
LOGICAL SCREEN DESCRIPTOR BLOCK
may include an optional GLOBAL COLOR TABLE (99.5% of the time this will be present)
optional NETSCAPE APPLICATION EXTENSION BLOCK(:-> surprise)
a stream of graphics (each graphic being composed of the following)
an optional GRAPHIC CONTROL BLOCK (one preceding each IMAGE)
a single IMAGE DESCRIPTOR or PLAIN TEXT BLOCK
which can include an optional LOCAL COLOR TABLE for an image
and the actual IMAGE or TEXT data table
GIF TRAILER ends the series of images

COMMENT BLOCKS may appear anywhere as they are ignored. (Do NOT place them before the Netscape Looping Extension!!)


edit:
The image file is TOO LARGE.
There are several ways to reduce the file size.
Here are some ways:

Reduce the dimensions so it's a little smaller on the screen

Reduce the amount of colors used. GIFs allow up to 256 colors and if you only use 25 for example it will reduce the size

Strip every other frame and double the time each remaining frame is displayed. This is the most drastic step but it may help

NO clue what this means lol so how about this can someone here make me the sig i want and make it fit

If you have the original PSD file I can fix it for you.

If you don't have the original .psd file then you will most likely need to get an entirely new signature
