Nah, the put too much shit on them, ads etc. Speaking of Portals, I can't use either on my new forum as both of them are still too unstable to use. Sucks.
Wow, that's terrible. That's about what I had back in 2000 as a beta tester for the cable company. Only a few of us were on it at the time, then it was released to everyone later on. I hope my forum doesn't take forever to load on that.
I've kept them on mine but when you have 75Mb internet you are faster than most sites can upload to you anyways. Hmm, should I upgrade to the 400Mb? Nah!
That's more on verifying than detecting it. Just divide width by height and refer to this chart:
1.33:1 = ( 4:3 )
1.78:1 = ( 16:9 )
1.85:1 = ( 37:20 )
2.20:1 = ( 11:5 )
2.35:1 = ( 47:20 )
