If the src attribute of the image tag is empty, I don't see how it
could really be anything _but_ imagemagick--otherwise, afaik you
should just get the original image. Try having a go at the image
processing tests in the install tool again, making sure that you've
first deleted the files in /typo3temp using the 'cleanup' section of
the install tool. Also, double check _all_ the image processing
settings in the 'All configuration' section.

The symptoms with imgtext that you describe above suggest that while
imagemagick _is_ working (all operations work with .gif files), it is
not able to successfully read/write some image formats. If, for
example, it's not built to read .jpg files, you might see the
behaviour you describe above: i.e. you get an image when no resizing
is needed (plain image, image with text above/below), but no image
when the image needs to be resized (image with text to left/right).

To test if this is what's going on, check to see if the images in the
working imgtext configurations are a different size in pixels than the
originals. If they are, then you know for certain that IM can read the
orignal and write the output formats.
