I came back from my holidays, with tons of photos taken with my new digital camera. Normally, I prefer to take pictures using the best quality and resolution, and this - of course - implies having bigger files to manage.
Often, at a good resolution, a single photo in JPG format takes more than 1 Mb, and this is not so comfortable if you want to send your pictures to your friends via email, or to put them on a web site. You have to reduce the quality of your pictures, resampling them at a lowe...

Q I am building a Windows® Forms application and need to be able to create graphical text on the fly. Basically, I want to create an image, add text to it, then use the new image later in the app.

A The first step in solving this problem is pretty easy. I created a simple form that allows you to enter a string of text, then enter the starting point for the text in the resulting output.

I have searched the web (via Google) for examples on how to convert a GIF image into a transparent GIF image without much success. What I wanted was there, just not in the way I wanted it.

Some of the methods I've seen on the web that converts a non-transparent GIF to a transparent GIF used unsafe code to perform the conversions. With luck, I stumbled across a couple of examples that performed the conversion without unsafe code, and I ran into Bob Powell's transparency page and voila, fo...

Wouldn't it be nice to use a base set of grayscale images and automatically apply a color wash to them to bring them in line with the customer's color scheme without fiddling with a graphics package?...

If you've been running your web site for more then a couple of months, you've probably noticed how quickly image files tend to accumulate. Even though we all try to give our files meaningful names, sometimes when you're looking through a directory full of image file names, it's not always easy to recall what a particular file is or what it was used for.

When that happens, I usually find myself repeatedly firing off a browser and requesting the image to see what it is. Well this little scr...
