Do you mean your camera has a SIM card, or does it actually use floppy disks?
In any case, with the pics on your computer, follow these steps.
When you're logged in to Fotki:
1) Click "Photo Albums" on the left side of the screen
2) Click "add photos" under the album of your choice.
3) Next screen click "fotki java uploader"
4) Under the "folders" tab, find the folder with your pics
5) under the "folder content" tab, click on the locations to find your pics and then click on "add to list", or add all if you want to upload all in that folder.
6) click "start upload" in lower right corner.
7) click "return to album" in popup
8) click on picture in album, click "share", click "more sharing options", then copy "code for forums" into the box here.
Hope that helps!
