When doing small icons, header graphics and the like for websites, is it better to use GIFs or PNGs? Obviously if transparency effects are required, then PNGs are definitely the way to go, and for larger, more photographic images I'd use JPEGs - but for normal web "furniture", which would you recommend and why? It may just be the tools...
Believe it or not I need a way of displaying animated gifs in Flex 3. This guy has a component for sale but it's Flex 2 only: http://dougmccune.com/blog/2007/01/19/how-to-load-animated-gifs-using-adobe-flex-20/. And I’ve implemented this example: http://www.bytearray.org/?p=95, but for larger gifs it’s very CPU intensive and causes the ...
I have a image upload form that should take image types (PNG, JPEG, GIF), resize it and then save it to a path. For some reason I can't get the PNG file types to work, it works fine with JPEG/GIF and the file is copied so it looks like it's something to do with how I'm creating the PNG. Does PNG creation in PHP require different para...

I've incorporated LIBPNG and ZLIB into my C software for a microcontroller project due to their nicely liberal license which permits such use without requiring me to disclose any of my code (it's very similar to BSD/MIT/APACHE, but with no attribution requirement). I'd like to look at using lossy image compression to save memory. The J...
I'm trying to dynamically generate a gif image of a specified size and color in an HttpHandler. For some reason, the image is being generated with a dithered color pattern rather than the solid color I expected the SolidBrush to create. The following code is the simplest I could find that exposes the problem. private void GenerateSqua...

So I have this GIF file on my desktop (it's a 52 card deck of poker cards). I have been working on a program that cuts it up into little acm.graphics.GImages of each card. Now, however, I want to write those GImages or pixel arrays to a file so that I can use them later. I thought it would be as straight forward as writing .txt files, bu...
I'm creating a indoor navigation application (with the intention that a user can store maps for different buildings in the phones file system). The application starts up by asking the user to select a map for the desired building. Once this has been selected, a file parser would be used to parse and convert the map data from the file. Wh...
I'd like to convert gif images to jpeg using Java.

We are working on a website and noticed that the GIF images(100kb - 200kb) are loading very slowly. The site is a static site with CSS/HTML. Does any one have any pointers to why the images might be loading slowly? Would using JPGs improve the performance? Here is the HTML code for that image: <div><img src="images/mainImg_3.gif"...
