Community promotion ads are small images shown in a site's sidebar to promote various related things - site blogs, events, and other Stack Exchange sites, to name a few. Only graduated sites (and a few beta sites) have them - so most betas don't. However, I'm not looking for us to host ads, but to make one. People are trickling into our new, quiet portion of the Internet, and it's important to let everyone know what this site is all about.
Here are some select formatting details from Stack Exchange, which are repeated in the submission threads for ads on other sites (e.g. here):
- The image that you create must be 300 x 250 pixels, or double that if high DPI.
- Must be GIF or PNG
- No animated GIFs
- Absolute limit on file size of 150 KB
- If the background of the image is white or partially white, there must be a 1px border (2px if high DPI) surrounding it.
The precise details for submission can be ironed out when the ad is submitted to various sites.
We obviously don't have a site design yet, and we should expect that for a really long time - long after graduation starts. However, we do have some options. For instance, we could use the default icon from the site proposal:
Alternatively, we could come up with our own design.
