It is available as a Debian  package and as an RPM package, but I 
couldn't find a Slackware package for it.
You can download the sources from: http://www.mbayer.de/html2text/

Micha suggest a different parser (pdftotext) - I will change it, and 
look into the horizontal scrolling problem.

I will fix that, TAB sounds interesting, I'll see if it can be easily done.

Does it happen only with large images, or with every image ?
Do you press CTRL+"+" very fast, or press onces, release the keys and 
then press again ? (it sounds funny, but maybe related to the problem).

No problem, how much "more" do you want ? is 5 times enough? 10 times ?

Did the previous version (1.1.7) handle uncompressed TIFF correctly ?
I did do a big change on the way images are loaded, but it seems the 
method in 1.1.7 was actually better....

I swear I will not rest until our internal viewer is the fastest in the
