It would help if you could describe what's NOT happening when you try to make pictures?

Start here, with some simple guidelines. What they said, stick to 150-300 DPI scans, no larger. If the scanner doesn't have that option, use 50% and see what you get.

Filenames even though we are into modern operation systems, the old 8.3 rules are good to stick with for the web. That's eight letters/numbers and a three letter extension.

chip001.jpg for example is very nice.

For the web you have three choices. Skip BMPs and you really have two choices. GIF or JPG. (not jpeg extension, even if it works sometimes)

So what you want to do is scan your chip and save it as chip001.jpg

Then you have two options. Put it up on your website, which you'll need to do for eBay unless they include free hosting for one image (I don't know I use my own site) or in the case of the BB you can link to your image on your site, or upload it to the BB storage system.

Advantage of JPG images is that they are compressed and smaller than a full size image. Use 80% compression if the software asks, if it doesn't ask, don't make things more complicated until you get rolling.

1) Make a scan
2) Name it with letters and numbers only, no spaces!
3) save it as a jpg (and remember where you saved it)
4) Put it on your website, or uploaded it to where it's going. There are size limits on the BB.

email me, I'm here all day, and happy to help in any way I can.

Personally I use all lower case names, so I don't have to make notes whether an image is chip001.jpg, CHIP001.JPG, CHIP001.jpg, or Chip001.Jpg which are all different when linking to an image on the web.
