I've got a basic output of the last 10 image assets in the sidebar, and currently each thumbnail is linking to the full size version of the image.

I want to link the thumbnails to the entry that contains that image, and I can't find anything that will do.

I know assets aren't necessarily tied to one entry, but as far as I know the client whose site it is doesn't re-use images, so there will only be one entry per asset. I just need a way to access the entry's URL.

Any ideas?

Are you using the images in the sidebar as widgets? My best guess in that case would be to edit each image widget to point to the entry url that you want it to go to.

Hope that helps.

AFAIK, MT doesn't keep track of what images have been used what entry, so I don't think there's a way to do what you're looking for. that doesn't rule out a plugin providing this kind of management, but not one i'm familiar with
