Bandwidth saving and image optimization !
For thumbnails I have used GIF format with each size ranging frm 12 - 25 KB. But only now I learn that G is better option considering size. Should I switch over to if yes how ? I mean what software to use and I am using wordpress, how can I chane the filename for every custom "thumbnail" url ? Please help !
I am a newbie and have no idea abt website optimization ! Within few days I may run out of bandwidth !
