Allright... This might get a little hacky...
First go to
http://spywaresucks.org/prox/ , download and set up Proxomitron (the helps on the site should be sufficient). Then add this filter to your set:
Name = "Destroy ALT texts on Apolyton fora"
Active = TRUE
URL = "apolyton.net/forums/"
Limit = 64
Match = "BORDER = 0 ALT = "*""
Replace = "BORDER=0"
(that means, cut'n'paste it to default.cfg and press load from disk)
It removes all the ALT texts from the images on your browser on Apolyton fora, thus making the thread width sufficiently small.
EDIT: It seems to screw some threads up... I'll try to add a bounds match in a moment.
EDIT2: I'll never understand how to get the bounds match working

. Anyway, this filter should do quite well... If there are still threads where you get ALT texts for long images, try expanding the byte limit. If something doesn't load properly with this, press "bypass" and reload the page.
EDIT3: Fixed the link...
EDIT4: Fixed the edit numbers
