Texture image sequences cannot properly use a sequence of images where the first image filename is "image zero", ie. the image filenames are zero indexed. Example:
image00.tga
image01.tga
image02.tga
image03.tga
Attempting to use image00.tga as the base image of an image sequence texture reverts to being a still image. Setting image01.tga and using a negative offset does not work either.
Steps to reproduce:
1. Create a series of numbered images where one image uses the number zero
2. Attempt to use the images as a sequence texture, starting from zero

This is a generic request to test your bug report and see if it is still an issue in 2.5alpha2 if so please let me know by making a comment in this report ie 'also in 2.5alpha2' and I will add it to the 2.5 bug list.
also in 2.5alpha2
It does look a bit better in 2.5 Alpha 2 - if I deselect "cyclic", and set an offset of -1, image00.tga will be used until image01.tga is - but with "cyclic" selected I have the same behaviour as in 2.49b.
The Python interface components are ImageUser.start_frame, ImageUser.offset, ImageUser.cyclic - thanks for looking at this!
Confirmed in rev. 28057. Had a bit of a look in the code there, there's some tricky stuff going on..
I'll also add that the strange math effect happens in the compositor, background image, and other places.
See http://projects.blender.org/tracker/?func=detail&aid=23558&group_id=9&atid=498 for example.
I don't think this was ever intended to work like this, so it's not a bug, but I guess it could be useful in some cases so this should probably be posted to www.blenderstorm.org or some other feature request channel.
Closing the report.
