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 am having problem in rendering data in my react native app.I need help. Actually there is a listing of around 3000 activities which i want to show in my app.The listing includes cards of different sizes depending on the content.I am currently using flatlist to render this dynamic content but the performance is very slow and blanks space appears after some scrolling as i scroll the listing down it gets slower. I have used the Recycler view as well but as my content cards are of dynamic sizes and recyler view limits from dynamic sizes.I really need help from experts and open to any suggestions.Thanks in advance.
I think this article would be a good starting point, it solved a lot of issues for me.

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 was looking at the Soundlcoud Widget docs
http://developers.soundcloud.com/docs/widget#
I noticed there is a parameter for 'download'. I tried it on the HTML5 sharing widget it didn't turn on the download link. Is there a way to show the Download link?
Example
http://w.soundcloud.com/player/?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F46911134&auto_play=false&show_artwork=true&color=ff7700&download=true&sharing=false
Thanks
This is actually the intended behaviour. A lot of the time, the widget is displayed in a relatively small frame, and showing all the buttons creates too much visual clutter. A redesign (to use icons, for example) is coming, but I can't give you a date on when that will be ready. In the meantime, the documentation will be updated.

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:

how to use images in your PDF documents
Disclaimer: I work for the vendor of the library.

I'd like to try and create a program playing a game. I.e. "a bot".
I want to be able to directly access the pixels on the screen. I.e. have my program "see" a game and then "make a move"(or at least draw a picture of what move it would make).
Both Windows and Linux advice is appreciated, though my guess is that it should be easier to do on Linux.
I'm guessing this could be done with some X/Gnome call?
I'm not afraid of C, even complex samples are welcome.
SDL is a cross-platform library that allows you to directly access framebuffer pixels. You can learn about accessing the pixels on screen through the pixel access example on the documentation wiki.
Generally speaking, bots don't see the game graphics but see the underlying data structure instead, unless you are trying to do something related to computer vision.
