Try loading this normal .jpg file in Internet Explorer 6.0. I get an error saying the picture won't load. Try it in any other browser and it works fine. What's wrong? The .jpg file is just a normal picture sitting on the web server. I can even create a simple web page: <a href="http://www.zodiacwheels.com/images/wheels/blackout_thumb.jp...
So, to simplify my life I want to be able to append from 1 to 7 additional characters on the end of some jpg images my program is processing*. These are dummy padding (fillers, etc - probably all 0x00) just to make the file size a multiple of 8 bytes for block encryption. Having tried this out with a few programs, it appears they are f...
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'm putting together a script to find remove duplicates in a large library of images. At the moment I'm doing a two pass filter of first finding files of the same size and then doing a sha256 on a 10240 byte piece of the file to get a fingerprint of the files with the same size (code here). It works well, but I'm guessing there are prob...
I'm looking for ways to determine the quality of a photography (jpg). The first thing that came into my mind was to compare the file-size to the amount of pixel stored within. Are there any other ways, for example to check the amount of noise in a jpg? Does anyone have a good reading link on this topic or any experience? By the way, the ...

I've worked my way through a number of interesting routing problems - turning a request URL into a hash, etc., but just out of curiosity, is there a way to tell the routing system that you want anything that comes under a certain url subpath to be served literally - without going through a controller? For instance, if I have /home/me/...
I'm trying to load preview thumbnails of high resolution images and the application needs to be able to load 100 hi rez images at one time. The only way i know how to do this is if I use the Loader class and I have to load the ENTIRE file and then scale down the image and use the data as an image preview. what i'd like to do is use imag...

I thought I could work this one out myself but I don't seem to be moving forward at all. Ok, the background: I need to create a Huffman tree of codes from the information provided by the FFC4, DHT (Define Huffman Table) header in a jpg file. The DHT header defines the Huffman table in this way: 1) A series of 16 bytes. Each byte defin...
I have an RTF file that I need to display to a user. I know that I need to convert it if I want to display it in the browser. I would like to be able to convert it to JPG so that I can take advantage of other code that I am using that uses ImageMagick to convert JPG to PDF. ImageMagick will convert a PDF to a JPG, but not an RTF :( I...
A project I am working on needs to be resized when the monitor resolution changes. Due to legacy code and other issues, we do it by using a custom library which scales all the components to the appropriate sizes when the resolution changes. However, when we scale some of the images/icons used in the project, they become blurry/fuzzy/ali...
I want to distribute a few images and not allow others to see them unless they are using my program. My intention will be to use JPG files in which I will alter the header so other image viewers cannot read them anymore. For example I can delete the bytes 7-10 which are the magic signature for JPG. Later, my program will reconstruct the ...
I retrieve .jpgs from my server and load them within my as3 app. I use Flash CS3, and am not using flex. Occasionally, some images will appear yellow and unreadable within the app. The actual original of the image is fine, and has no such yellowing, yet when I load the image in flash it appears yellow. This seems independent of size, cau...
