paste html link with thumbnail into page content

[s3t]

I've overcame this issue by using jQuery. Quite 'quick 'n dirty'.
I search <img> tags which link to /thumbs/ directory, and then wrap them with <a> tags linking to full-sized image.

This is not google-friendly way of doing things (as google won't index large images), but i'm happy with it.
