What is "good resolution"?  With your budget, you will only get HD screen (1366x768).
15" with your budget should be enough for "online, movie, browsing".
Editing picture, well, depends on your file size and what kind of job you do.

The Toshiba is the most powerful among the above 
Prices are RSP, negotiable.

Don't think too much about "brand". Each brand has lots of models, some are good, some are not good value for money, ... (hope you get the picture).
The Toshiba listed is good value since the price is good for its spec and come with 3 years warranty (longer than any other brands listed standard spec (other brand you have to pay more to extend to 3 years)).

For your budget, you can only get HD screen unfortunately. If you have seen 14" laptop before, most (if not all) are HD screen. For casual online, HD screen is sufficient.
For 15", if you want better screen, you need to pay close to RM3k.
For example,
Acer
V3-571G-736b8G1T, i7-3630QM + Nvidia GT730M(DDR3) + (1920x1080 IPS) @RM2899[2.6kg], 8GB, 1TB, W8
This has 1 of the nicest screen around. FHD panel (can display 1080p video), great colour and contrast.

The other model can process higher resolution, you just have to connect to external display or TV that support those higher resolution (normally through HDMI port).

How should I put this? 
Supposed you took a picture using your smartphone or camera. You transfer the file to your laptop. The picture pop up on the laptop screen. You edit, make adjustment, everything look nice. Then you print. Holy ***, the print does not look like what it show on the screen (colour and contrast all off)
That is because most of the laptop screen are not calibrate properly to show the colour correctly right out of factory. (Even on expensive model like MacBook )
For casual use, some users don't really care. But if you are willing to spend a little bit of money (~RM60), you could get your laptop screen calibrated using professional tool.
