Remember to read the Forum Rules for your Avatar and Signature limitations.
Quick bullet list:
- Limited to a max of 150x150. Ones larger won't work or will be auto-scaled to a smaller size.
- If you're using an animated GIF, keep the file size as low as possible. Larger "movie"-type files will be removed if it compromises forum load times.
- GIF, JPG and PNG formats are permitted
- 400x100 size limit!
- If you use your maximum signature image size you are limited to TWO lines of the default text size in addition to the image.
- Same "file size" rule follows with the sig images, too: if it slows down the forum it's likely to get axed.
