Sig Files:
Signiture images should be no more than 500 pixels wide and 100 pixels high. wide signature files muck up the board layout on smaller monitor resolutions, and tall images create unnecessary scrolling. Ask yourself: will anyone actually CARE about what's in your 800X600 image? The answer is probably an unqualified NO.
The size of a sig file image should be no more than 20k.
Avatars:
No larger than 100x100 pixels. They will be automatically sized down by the board software, but will still have the horrendous download times associated with the larger image that they are.
Please try to keep avatar sizes (in kilobytes) under
20k.
So danbag, please note, you do need to change your avatar. We try to be a little flexible, but that's still too large. Keep in mind that some people are still using dial-up, and right now, your avatar is the single biggest element of this page.
