Intersting.....
The _tp.gif file is only 1217 bytes in size (checking its Properties).
The _o.gif file is 101046 byes in size and is also 250x250.
Hmmmm.....how about a little Revise listing work in ebay and substitute the _o.gif file reference(s) for the _tp file. That shouldn't be too tuff to locate in HTML mode.
You can use ebay PREVIEW before you submit the revise to check results.
