Hyperlinks in image Title or description

[JohnM-UK]

This is similar to another topic I found but this is a bit different and that other one was 'solved'. Anyway what I wanted to do was, instead of the 'Paypal buy picture' or 'shopping cart' add-ons/mods/plug-ins was add a simple 'Buy' hyperlink, (which would be a link to the ebay page in the ebay shop I hope to be having) in the title or description, or other useful links. Example:

Two Mile Bottom 
Yes, it's really called that! This particular little area of Thetford Forest. It's 2 miles from Thetford, where the 'Bottom' comes from though, I don't know!

What about using bbcode in the description?
