**** DPI (dots per inch) is a measurement of printer resolution, though it is commonly applied, somewhat inappropriately, to monitors, scanners and even digital cameras.
For printers, the DPI specification indicates the number of dots per inch that the printer is capable of achieving to form text or graphics on the printed page. The higher the DPI, the more refined the text or image will appear. To save ink, a low DPI is often used for draft copies or routine paperwork. This setting might be 300 or even 150 DPI. High resolution starts at 600 DPI for standard printers, and can far exceed that for color printers designed for turning out digital photography or other high-resolution images. ****
So, please ask the question again, and say what the resolution of your Images could be 380 kB for example, and what do you call best quality of an Image ???
Sunil, DPI isn't really relevant. Your display is sized in pixels and your images are best supplied in the same resolution (regardless of DPI setting) that you wish to use them.
Hi Paul and aktell,
My application having import image for use in Photo Album so when we import file in Adobe AIR application
we had code for create three folder 1) Low Resolution - This folder image used in Thumbnail view(imaze size 300 X 150)
2) Mid Resolution - This folder image used in slideshow and it's image size is 1000 X 600
3)High Resolution - This folder image used in report generation and its image size is original as user import from original source.
My main issue is make only one folder which having best quality image ,without pixalated when we used in big container which having 1200 X1200 size and showing image with best quality and also it will not big size so if user import 500 hunderd images which cannot degrade performance of application.
If you don't want' performance slowdown, only load the large images when necessary. Use the server side to process larger images to create thumbnails and intermediate sizes from the larger images.
If all the images are static, you can batch process them using Photoshop or a similar application.
