PhotoPlog Lite uses the GD library for image processing, but it is currently not possible to process BMP files using the GD library. Not sure why, but perhaps it is because BMP files tend to be rather large and might lend more to size and timeout issues. That said, you could edit files like Nitro suggests, using this:
Code:
Content visible to registered users only.
Instead of this:
Code:
Content visible to registered users only.
And using this:
Code:
Content visible to registered users only.
Instead of this:
Code:
Content visible to registered users only.
Though there is still the thumbs issue, where you could use width / height attributes to resize, but basically there would need to be some rewrite of the code, whether through the use of the ImageMagick program or custom BMP functions, to account for the lack of BMP support in the GD library.
