well after posting the photos above , i guess i not really into group poster, only prefer individual or mv poster. 8r cost more than rm 6 while 4r only cost 35 cent. it's a huge price gap . for photo frame , 8r is definitely a better choice. i printed 8r once, but my experience tells me i should has choose the matte finish instead of gloss finish. why? It sticks to the glass when framed.
Gloss Finish: This is the most common photo finish with a laminate surface that most people are used to. Great at showing fine detail and vibrant colours this finish is available in 6x4, 5x7 and 6x8 print sizes. p/s: Glossy finish is a good choice when printing everyday snapshots or photos with rich vibrant colors. The disadvantage is the most likely surface to stick to the glass when framed.
Matte Finish: A textured finish that is very resistant to scratches and fingerprints. Matte is ideal for use in picture frames where the glass would cause glare if used with a gloss image. Also used in larger print sizes to reduce glare across a larger surface.
p/s: Matte finish is a good alternative when printing black and white photos, photos that will be handled regularly, or photos that will be framed and hung on the wall.
As to which is better, which i have learn my lesson..........I prefer glossy prints for 3x5" and 4x6" prints in which i put them in my photo album , matte surface for wallets (harder to scratch), and matte surfaces for any print 5x7 or larger that is intended for framing which i haven't done yet.
p/s: by the way, u still haven't tell me which 2 pictures u choose. The cartoons also nice what;

i printed out 100 4r matte pics of t-ara and eunjung.. while my fren did another 100 together for his SNSD pics. bargained with the shop lady, she gave me 2 free 8R prints all aso matte! ;D so yeah... now gonna get a nice frame for my eunjung and jiyeon pic ;D used these two photos instead ;D
