Ubuntu :: Firefox / Web Browser Can't Open Downloaded Imasges

Firefox / Web Browser Can't ipen downloaded images.I have been using Firefox 3.0 with good success, and recently switched to Firefox 3.5 (unbranded version,called A Web Browser).I was looking around in Google images and downloading a few images in Web Browser 3.5, when my problems began.Firefox and Web Browser run off the same profile, and neither browser will open image files correctly.I call Web Browser WB for short.All of a sudden I cannot open jpg images.I saved image as and when the download was complete, I tried to open it.WB needed an application to open with, so I selected to open the containing folder instead. WB needed an application to open with again.

Not knowing the name of the Ubuntu image viewer, (which is eog for Eye of Gnome) I went over to /usr/bin and selected the document viewer, evince, to open the jpg image, which didn't work, so I selected nautilus as the application to open the folder with.Now I can open the folder all right, and from there, I can open the jpg picture from within that folder, but I am now told in the WB and Firefox download window that /path/ to/picture.jpg is not a folder in response to my trying to open the downloaded image.I performed some other checks:I can successfully download and open a pdf document;I cannot open a png or gif image, for they are not folders.

A check of Preferences and Applications tab shows no listing for jpg, gif or png or the word image under content type. There is no provision there to create a new entry, either.I checked and compared Firefox Preferences Applications tab with that of Web Browser. They appear to be identical in content.What do I do next? I will log out of 9.04 and back in again, and if that doesn't work, I will restart the computer after I finish my post. Then I will come back with the findings.
