[K12OSN] FF and big images freeze

[Mella]

Hello!

I have big problems with big jpg imagages in Firefox.
If I open big image, it get half of them and then freezes. Only way to 
continue is switch terminal off. Sometimes it just closes FF.

I noticed that not all terminals have such behaviour.
I have problem with Compaq Deskpro SFF Celeron 300A /64MB RAM/Ati rage 
pro turbo/intel 100 NIC.

And no problem with Compaq Deskpro SFF P3 /128MB RAM/Ati rage pro 
turbo/intel 100 NIC.
Also all OK with IBM T20 laptop.

I don't know where is problem.  With FC2 was all ok. With FC4 and 5 I 
have problems.
Any ideas?
