    Default WEBP plugin is broken

    IrfanView 4.54 32-bit,
    WEBP.DLL version 4.54 32-bit, size 255*488 bytes, SHA1: 8E26001F45541FD92AD284184ACEB1DB2A311A84

    Error message:

    ---------------------------
    IrfanView
    ---------------------------
    c:\Documents and Settings\PC\Local settings\Temp\f_000018.webp : Decode error !

    Can't load PlugIn: "WEBP.DLL" !
    Please install or update PlugIns from IrfanView homepage
    and/or
    enable the PlugIn in 'Help->PlugIns' menu.
    (32 bit)

    ---------------------------

    Info in 'Help->PlugIns' menu shows

    Previous version (4.51) works OK with the same webp image.

    No problem here. Can you load any other WebP images? If so, then we need the specific image for testing.

    This is my webp.dll for 4.54

    Hi,
    your WEBP.DLL is okay, mine has the same SHA1 Hashcode. So probably the image is somehow broken.

    What is your operating system? The newly compiled plugins are no longer compatible with WinXP/2003, and have dependencies in KERNEL32 for InitializeCriticalSectionEx, InitializeConditionVariable, WakeConditionVariable, SleepConditionVariableCS.

    WebP images save and load if I rename those imports with GetExitCodeThread (a fix for another problem where the imported functions were known to be unused), although the File-Open preview crashes.

    They should remove XP from the list of supported systems on www.irfanview.com.

    I don't think that is necessary as long as a standard installation without the extra plugins still works on XP.

    I noticed that the Plugins page still lists WebP.dll 4.51. Perhaps that page should state that some plugins do not work on XP? Have you emailed Irfan Skiljan about this issue?
