Current result:

In step2, non photo files were added to wallpaper list, fortunately, these files don't take effect when try to select them.

Expect result:

In step2, non photo files should not be added to wallpaper list, it should filter non photos files when adding to wallpaper.

Do you mean that the file extensions weren't image extensions or that the were properly named image files with non-image data inside them?

[ToddBrandt (todd-e-brandt)]

Oh man, ok nevermind, I've confirmed the error. IT seems to pull in everything despite the filter I added.

[ToddBrandt (todd-e-brandt)]

Ok, the problem was in the filter, it was a dumb little programming mistake. It now filters on these types (like it should have all along):

        ".jpg",
        ".jpeg",
        ".gif",
        ".png",
        ".bmp",

Hi, todd
I verified the issue in moblin-applets 0.66-0ubuntu5, here is the result:
1. Non photo files with extension name other than ".jpg", ".jpeg", ".gif", ".png", ".bmp" can not be added into wallpaper list, it's correct and the issue is fixed.
2. Fake photo files (non photo files with extension name ".jpg", ".jpeg", ".gif", ".png", ".bmp") can be added into wallpaper list, it's wrong behavior, it should be fixed.
E.g. change a file test.txt to test.bmp, the file be added into wallpaper, and shows "Thumbnail loading..." under the file in the wallpaper list.
3. Photo files with extension name other than ".jpg", ".jpeg", ".gif", ".png", ".bmp" or without extension can not be added into wallpaper list, it's still wrong behavior, it should be fixed. For this issue, I file a new bug #235382.
