Greetings and welcome to my tutorial on how to follow the rules for signature sizes, below is a direct quote of those rules:
Below are various options to allow you to make your signatures much smaller in file size without losing much (if any) quality of the finished image...

Put simply it is simply to Smush It (see below) but this seems to be a bit more stable and give better results according to some, try it for yourself and see what happens.
Smush-It Provided By Yahoo!
(the url has been blocked due to a swear word within the name so just add "it" at the end )
It is a free service provided by Yahoo! and allows you to greatly reduce the size of uploaded images. The image you upload is only stored for a short time allowing you to re-download it
Below is an example for you...
Before being Smushed (33.10KB).
After being Smushed (16.66KB).
As you can see there is a decent difference between the two so I hope this helps folks out there who are/were struggling in getting their signature images to comply with the forum rules
For those of you who have Photoshop then you can do it yourself by doing the following.
1. With Photoshop open and your image loaded press "File" and select "Save for Web & Devices" (the image shows Photoshop CS5).
2. Now make the needed changes for the image (make yours look like mine):
3. Now press the "Save" button and choose where to save it and you are done!
Here is a before and after sample of using the Photoshop method:
Before being Photoshopped (91.2KB).
After being Photoshopped (19.4KB).
Another similar option to that of Photoshop is Paint.net which is freely available for download and can be gotten from this link.
