If any of you have a problem with huge dataset for aerial photo, read this source to compress your data using GDAL.
For me, it works by simply create a *.bat file in notepad++ of mentioned code. If you have a lot of photos, just do it in a batch file by making a list for the whole photos.
As a summary, do this following step:

If you get more confuse, just compress using Adobe photoshop. xD
