Is it better coding practice to define an images size in the img tag's width and height attributes? <img src="images/academia_vs_business.png" width="740" height="382" alt="" /> Or in the CSS style with width/height? <img src="images/academia_vs_business.png" style="width:740px; height:382px;" alt="" /> Or both? <img src="images/a...
I'm trying to export a copy of the Explain Plan from Oracle SQL Developer 2.1.0.63 All I get out is a html file named what I specify, then a newly created folder in the same directory called "images", which is empty.

Using JQuery JEditable, I have the following code below which allows the user to create virtual post-it notes, so to speak, and I'm trying to make it so that beside each div created, a delete image that the user can simply click on. I feel that I'm almost there, I'm just missing something. As of right now the image appears only on the ri...
Hello, May I know what are the ways to calculate the length of 1 pixel in centimeters? The images that I have are 640x480.

Hello. I am trying to make a program that outputs a 8-bit grayscale image to bmp file. I have found out that 8-bit BMP files are indexed. Is it possible to omit the color table and just put values instead of indexes in the color table? Or BMP format does not allow this? ...
I am supposed to write a program that gets some PNG images from the user, does some simple edits like rotation and saves them inside a JAR file so that it can use the images as resources. The problem is when I open, say an 80kb image and then save it with C#, I get an image with the same quality but for 130kb space. And because it has to...
I am trying to read in the pixel data from an image file as a byte[], for in-memory storage. (The byte array will later be fed to a bitmap image object, but I want the data in memory so that there's no I/O holdup.) This is what I'm currently doing: private byte[] GetImageBytes(Uri imageUri) { //arraySize and stride previously de...
I need to display an image, which I've done without problems before, but today I decided to be tricky and use "add as link" instead. Well, now I get: The file Images/hello.png is not part of the project or its 'Build Action' property is not set to 'Resource'. Wait... its Build Action is set to Resource. I've seen a Silverlight soluti...

I'm merging multiple small images into a rectangular mosaic.. When dealing with a small number of source images it turns out fine: grab.by/2Y4W (sorry, I'm new and am not allowed to post multiple hyperlinks) But when dealing with a larger number of sources it turns out a sepia like effect: http://grab.by/2Y4P Is there any technique I ...
