I've been using firefox with the downthemall extension to download .jpg and .wmv files. I decided to give Opera a chance, any recomendations for a program to duplicate downthemall with Opera?

Good call....Opera is the best. You can get a program called OperaGet that integrates FlashGet (you need it too) into Opera....here:

Or, you can get Mihov Pic Downloader that does pretty much the same thing, just simpler and it's free. Get that one here:

Also make sure to tweak all the settings in *Preferences* using the forums as a guide....like this one:
