Hyperlink in options

I have built a furniture shop using OC 1.5.5.1

Among the options, the customer has to choose a certain color or texture which is sometimes shown in an image.

The link to this image is now in the product description.

See for example this page: http://www.arredacasatua.it/letti-imbottiti-amaranto
There is a field to input the texture id: "Colore Tessuto o Ecopelle (inserire codice tessuto)" and the link to the image is in the product description: "Consulta il campionario Tessuti ed Ecopelle".

The shop owner is afraid this link is not visible enough.
Obviously it may be typed at the beginning of the description instead of the end, but it would not be sufficient.

Is there a way to place the link before the options or somewhere in the middle?

Please note, there is not a single image to be linked otherwise I would edit the template product page hard-coding it: sometimes this link must not be placed and it may link to different images.

Thanks in advance for your attention and kind regards to all the OC community.
