nowHello,
Have anyone experience with the DG random image plugin?
I have a problem with the link from image to page.
In my right sidebar, i have the image displayed randomly by the plugin. Everything looks perfect. Except that when I click on the image, i'm directed to the home page of the site and not the parent subpage containing the gallery from which the image is taken.
The title of the image displayed when mouse is hover is correct.
Have a look here http://buvezmadison.com/site
I managed to display the title of the page containing the list of the subpages (thumbnails, using autonav plugin) and link it to that page.But that's pretty the best i can do with php (and it might even be totally a "crappy" way of coding… sorry sir!)
I tried it with different permalink types but nothing i tried worked…
Can anyone maybe help me? Thanks a lot.
here under is the code of the plugin…
