how to prepare clear and clarity UI design with lower image file size in photoshop for iphone UI?
In my Iphone app due to large size images my app size increased enormously.So Is there any other way to reduce the size of the images but i need the clarity shouldn't change..?

Photoshop usually does a pretty good job of creating efficient images, however, you can normally losslessly compress them further using Yahoo's smush.it tool or a command line tool. Personally I use optipng which you can install via MacPorts.
You can also experiment with removing the #2x images entirely and just submitting with 2x resolution normal images. In most cases, the non-retina devices will downsample the larger images, but always worth testing on an actual device first.

I truly need help in Adobe Illustrator PDF. I have many small PNG files saved from lost vector line drawings.
The problem is that PDF scales up any image file (JPEG or PNG alike) when saved in Adobe Illustrator. Although such PNG images are as big as 1920 pixels width size, they are about 50 KB. But when exporting a PDF file, the PDF file becomes almost 9 MB. Is there a way to configure the Illustrator PDF to not alter the image type or size, but rather embedding it as is? I also don't want it linked to an outside file, but rather embedded as is, without scaling it up to 9 MB.
I looked through the PDF settings, but there isn't anything to give me the option to embed images without scaling up. Even setting it to 72 ppi doesn't make a big difference.

I have to make a website that will render multiple images at once like a shirt which will have multiple parts like a collar, sleeves, etc. I have to combine all these images at once and show the image of the whole shirt.
How could I do this as fast as possible to give the user a better experience?
I recommend you to use a npm module called sharp. By using that, you can resize your image to smaller, which will make your image loaded faster. Besides, you can serve dynamic image based on client device resolution, and that could obviously decrease the time image loaded.
sharp website: https://github.com/lovell/sharp
just you can load images from low quality to high quality using progressive jpeg-https://www.hostinger.in/tutorials/website/improving-website-performance-using-progressive-jpeg-images
if you want load your images faster you can do image optimization:

I have a few copies of textbooks this semester on PDF. These are 1000 page computer science textbooks full of graphics. When I downloaded it, it took just a few seconds which was amazing, I thought something had gone wrong. The entire textbook was 9.7 MB. I opened it up and sure enough, the entire textbook was there, all images and everything were loaded instantly (and I have a really terrible internet connection)
I am just wondering what amazing compression technique allows you to store 1000 pages of a textbook in under 10 MB?
Here is a screenshot of the file properties, I am so baffled.
A typical text page is between 3k and 6k tokens. So the text of your 1000 page book would fit in 6MB even without compression.
Normal compression tools can reduce plain ASCII text with something like 60-80%.
So lets say it's 75%, then you need 0.25 x 6MB = 1.5MB for the text. That leaves 8.5 MB for the pictures.
For vector based images like svg that's a lot, they are small and compress as well as text. But 8.5 MB does not leave room for a lot of embedded bitmaps.

Hey I am trying to design an interface for android application. Since I am a beginner to Android and Photoshop, I am having a few issues.
Most important of them is that I try to draw on larger than required canvas ( say, A4 siza; because i am not used to precise drawing) and then duplicate those high resolution (300dpi) layers to a smaller canvas with high resolution to create nine-patch files.
But I am unable to copy those layers; nothing shows up on canvas even if I have layers in the side box.
I have tried it multiple times but same result. Kindly guide me how to properly make a nine-patch image?

I regularly process shipping labels that come from the shipping company as PDFs. Before printing them, we add to each one:
a white vector box to block out part of the label
an image of our logo in a different spot
These additions are always in exactly the same spot on the page.
I would love to be able to script this in some way. I'm pretty flexible with options -- I have an iMac, a Windows 7 machine and a Ubuntu server in the house.
Any suggestions?
I would say you have plenty of options here.
There are a lot of PDF libraries out there and many of them can read existing PDFs. If you are fine with commercial libraries and are willing to use .NET stack for the task then I can recommend you Docotic.Pdf library.
Here are samples:
