I'm feeling like a bit of a dweeb these days with regard to my Silverstripe capabilities, so this could be yet another problem that has a simple solution. But, as I can't figure it out, I appreciate in advance any help.
I followed the advice the imagesuplod recipe (http://doc.silverstripe.org/doku.php?id=recipes:imageupload), and it worked to add the field and allow me to upload my banner photo. The photo appears just fine.
The problem is that now all my other images are gone.
After trying all I could figure out to try, I removed the field, rebuilt the database, and then tried again.
The images are still gone.
I removed the variable from my page.ss. I've double-checked, made test changes to, and replaced my CSS. I've flushed the cache (/?flush=all) and deleted the obsolete files in the database.
What am I not considering?
