I've created a gallery of the various QSL cards that have been uploaded to the Wiki here:
http://www.hfunderground.com/wiki/Pirate_QSL_CollectionAdditional scans of QSLs (or uploads of eQSLs) are welcome. Use the Upload File link on the left side of the page to upload your image. Then go to the URL I gave above, click the edit link at the top, and add an entry for your image. Look at the entries already on the page as an example of how they should be formatted.
Here's an example:
Image:Kipm.jpg |[[KIPM]]
After Image: you put the name of the file you uploaded. Then inside of the [[ and ]] tags you put the name of the pirate station. You should use the exact spelling of the station if it is already in the Wiki, so clicking on the name next to the picture will take you to the station's page in the Wiki. Copying an entry, pasting it, and editing the two names may be the easiest option.
